EDIT: *SPOILER ALERT!* Sorry guys, didn't expect this to be at the top of the comments! Well, if it's not gold, at least the cards look really nice, and now we know they're pretty dang resistant, so at least he can keep them for fun! Plus, even though nothing was refined, this really was an interesting video to watch. It's always good to see how to know things aren't going right!
I was immediately suspicious when it said "Laboratory Report" but didn't have the name of a specific laboratory. The report # is probably identical for each pack -- a quick way to spot fakes. Edit: Just looked up some online and both the cheap ones and the $80 ones have photos showing the same report #. Makes me wonder if there was ever a legitimate product with this design.
I looked up that model on eBay and there are a few for sale in the 15-20k range (used). I would hope he paid more in that range than the MSRP. Still crazy expensive for something handheld though.
What I appreciate about your videos is that you're not just some kind of gold-crazed prospector, you're genuinely interested in the chemicals and processes over all.
William Shreckengost there are paper decks that sell for that price anyways. No need for the company to be shady about it when they already have a good product. Its like, what were they thinking
This is my new name, That was my thought exactly! These are really nice (and clearly VERY resistant!) cards, I would love them in my collection just because they look great, but if anything, this video proves that if you get them at a decent price, they're very functional as well! Plus, knowing it's not real gold makes you not afraid of wear and tear!
All good points here. Thanks for the tip on the alternate backs, btw. I think I'll go ahead and grab one after all (seeing $3.40 for a lattice back), as they're clearly resistant to fluid ingress, and friends might mistakenly assume that I'm just some sort of turbo-baller with real gold playing cards.
nice video, and you exposed a fake company in the process. I hope someone uses your video to take action against that company if possible. its not right for them to be allowed to trick people into buying that crap even if it was cheap, they still think its real gold.
They might be able to get away with it if there's an amount of gold in the cards so small it's basically undetectable, which I suspect they may have done.
Moreover, quite possibly an outright counterfeit. In this case, the name of the company printed on the cards is irrelevant since that company had nothing to do with it, and honestly they're just as upset if not more so about someone selling counterfeits of their products as we are about buying them. Unfortunately, there's a pretty big problem with counterfeiting these sorts of products, especially if they're sold online, and yes, a lot of it is coming from China.
NewtSniper Contains at least 1 atom of 24 karot gold! Which is probably true about every card deck ever made. If you consider that a deck of cards would have 10^21 to 10^22 atoms in it, well, that's a LOT of digits. I can't conceive of that amount of material not containing some small number of stray gold atoms as "impurities". Even what's almost certainly the most pure material known to mankind, chip grade silicon, is only pure out to 12 nines or so, meaning you have 10 digits left to work with, so if those impurities contain at least 1 part in 10 billion being gold, you would expect a deck of cards sized piece of chip grade silicon to contain at least one atom of gold.
You really expect something that elaborate? Your the type of person who buys that crap on Amazon and gives it a bad review because it's crap...... Never could understand those people. "I bought a $20 knock-off Apple Watch and it's not exactly like the real Apple Watch!" "1 star!!!"
@@dphorgan Don't you think that's a bit harsh? "I know you're just thinking out loud about ways to authenticate this product, but no, I'm going to accuse you of being a naive idiot who ruins everything for everyone!"
I love the refining series almost as much as the beekeeping videos! Well, at least one prayer was answered, let's hope he goes back to the other series as well!
I've purchased a number off of items off of amazon, most of them electrical connectors of various sorts and most of them have had no gold in them at all (I have access to the same XRF analyzer you have in my lab and can measure plating thickness via metallography). I posted the results in my reviews of those products and on a few other sites that sell the products and a year later have found those products are no longer available from those sites and in some cases the store no longer sells products from that manufacturer.
Cody, huge fan. You inspired me to start keeping bees this season, and I love your videos about refining -- mainly for the chemistry. I would love to see some videos about how to produce basic chemical reactants from natural or readily available materials. For example, making your own nitric acid, or recovering elemental sulphur from ore, or the iodine from sea kelp. Thanks for the videos!
Thank you for still showing the true reaction after the cards failed to yield anything. Golds not cheap and I hope you can recover as much as you can. I really love your channels and I hope you never stop doing what you're doing.
If they wanted to make gold plated cards that you could actually play a game with more than once without destroying them, the gold layer would certainly have to be beneath something. If I had to guess, I'd assume they're using something like PETE, which is the type of plastic soft drink bottles are made of. One of its propertities (which is probably very relevant to being food safe, actually) is that it's pretty innert and most common organic solvents (such as your paint thinner) won't touch it. Even with solvents that DO work (DCM seems to be a common recommendation. More specifically to PET family plastics, phenols, as well as DMSO and nitrobenzene), you will probably have to heat it up close to the solvent's boiling point and then wait a few hours.
Keldor314 thanks for that. It probably explains why I met with disaster trying to get the coating off a beer can. The solvents and paint stripper I tried had no effect. I tried burning it off with an ordinary butane/propane torch and the aluminium melted. Looks like I'll need to spend hours with fine emery.
alarm bells ring for me when i saw the plastic as not many elements can be plated to plastic and gold is one of them as plastic cant conduct the current needed for electrolisis.
Stoned Savage! The thought is that it was gold foil not gold plated, gold foil is essentially extremely thin sheets of gold that can be glued to a surface.
A lot of the time you start a process like this with electroless deposition of metal to deposit a thin seed layer. Then move on to electrodeposition. That's how you get those shiny chrome plated plastics.
I'm just curious whether you checked that the certificate itself was gold plated? I know that it's a common tactic in the more unscrupulous sects of the leather industry to use a patch of real leather that says that it's real leather as the tag on an artificial leather jacket so that customers think the tag is referring to the whole jacket rather than just the tag itself, and something similar could've occurred here?
well, you dont have to touch them, xray seems to be enough. Still wouldnt consider a scam though as you couldnt really gold plate 52 playing cards with 24K gold for 5 bucks. If the 80 dollar one was fake aswell, that would indeed be a scam.
Great video, you sound a little demotivated or tired. I know everyone has struggles and I just want to say that your videos are always high quality and of excellent information and good science. Thank you and please keep doing what you are doing. You are adding scientifically backed up knowledge to the internet and enhancing and advancing anyone who is subscribed to your channel.
A wonderful demonstration Master Cody! I've never watched gold leaf dissolve in iodine, that was spectacular! Sorry about the cards, can't wait to see what's next!
That was actually really sad to learn. I hope the company that's selling the fraudulent cards is taken down. However, you still managed to make an interesting video out of it! I can't wait for more videos of this series, hopefully with legitimate materials next time. =)
I liked this style of video a lot. I know it would be tough, but this sort of detective kind of work is quite intriguing. Even grabbing a rock sample from the mine and finding the concentration of each mineral in it using this kind of chemical reaction would be very interesting.
It could be alternating thin layers of Al2O3 and SiO2. If you choose transparent layers carefully and alternate them with the right thicknesses you can create coatings with all sorts of optical properties. Metallic looking, colour filters, AR filters etc.
Maybe they were copper plated first then a super thin layer of zinc. Zinc plated onto copper is known to actually alloy with it on the surface creating a nice shiny golden brass. Ask nurdrage
I love your regular gold refining series, but this was far cooler. doing failure analysis and deductive reasoning within the specific realm of chemistry is greatly interesting. I would love to see you do more episodes on analytical chemistry!
The only solid gold cards I know of are from Mitsubishi Materials. They produced several sets of Hello Kitty themed card decks for the 33rd anniversary of Hello Kitty which were made of fine gold rolled several microns thick then covered in plastic. They also produce printed fine gold business cards, which are made of paper roll-coated in one gram of fine gold.
What if the certificate of authenticity is the only thing that's actually authentic? Did you test that or only one of the actual cards? That'd be pretty funny, and they wouldn't technically be lying. The certificate only says that there is genuine gold somewhere inside the deck, not that each card genuinely has gold.
kurtu5 Actually, there'd have to be actual gold foil, since that's what the certificate says. It could be an incredibly small piece, but it would have to be gold foil or leaf, not just gold in general.
Not sure what the lower bound "metal leaf' has before it ceases to be 'metal leaf'. Perhaps to be considered leaf, it must first be beaten as a manufacturing step, which would distinguish it from plating. If you split it down such that you only had one atom, is it then leaf? More likely there is a speck of leaf with quadrillions of atoms somewhere in the certificate. The cost to precisely place only one atom would be incredibly high.
It might just be all about the wording that is on that guarantee. It might be that the gold that is on it is 24k gold but it doesn't necessarily mean that the entire card is gold plated. what I mean by that is if you look at the crowns on the face cards they are a slightly different colour from the rest of the cards front and backs. I would check those crowns and see if they might be the only gold plated parts on those cards. Ideally thought I would recommend turning the cards to ash, and then treating the ash with a solution of AR and then testing that solution with stannous chloride to see if any precious metals are present. Or if you want to use your XRF just test the ashes prior to treating with AR.
Incorrect, XRF's only detect what is on the surface or extremely minutely below the surface, also I mentioned to test the crown of the face cards as the only cards that was tested was the 6 of clubs. to test the entirety of a sample you would need to use another method like fire assay or ICP
Yeah he basically describes where it is on his videos where he takes long distance videos across the valley. One thing is, he doesn't actually live there, his father does, and the other thing is his dad would probably shoot anyone that came by looking to hang out with Cody ;)
Can you do a series where you refine something starting from scratch? Like you take something that needs chemicals to refine but make those chemicals from scratch using only tools and no purchased chemicals aside from water.
Cody'sLab But if the reaction is between the sodium hydroxide and iodine then it would make sense to let that happen before adding the hydrochloric acid which will consume all the sodium hydroxide.
HCl + NaOH --> H20 + NaCl He was destroying the acid he added that the process could use in order to create Na ions when he could have just added table salt (NaCl) to begin with.
Hey Cody, I have watched this video like a hundred thousand times and I got to thinking..... Would you be interesting in revisiting the playing cards? The cheap ones of course and see if you can render the cards down and identify the metal they are made of... Perhaps if you could get the "plating" off of all of them and try to furnace it down to burn off the combustibles like the coating and such and see if you get some type of metal in the end? I miss these videos, I think it would be cool to see how to render all metals from ore. I live on a mountain and have a lot of rock to identify around the property.... You know what I think would also be neat, make a bar of fools gold, since the stuff turns to ash it would be a challenge I think.... Good excuse to make more crucibles and cupules. I don't know, like I said I miss the refining videos. If you could maybe use some tactics from Grants old videos and also make a sustainable forge for those of us that can't but they better stuff.
I finished graphic school in Offset Printing and these cards that aren't gold are just golden colored mass that is rich in some type of metal and on top of it we usually print a layer of coating.
I would really love to see a video in this series dedicated solely to iridium... aside from being a big challenge, it's also a super cool element in that basically 100% of it that you'll find anywhere near the earth's surface is guaranteed to have fallen from space after the earth cooled and solidified. So if you get a sample of it, you know it's pretty much pure meteorite atoms.
I've used a vinyl wrap almost identical to the pattern on the box. I'd guess it's a 3M vinyl sheet with the carbon weave pattern in a gold color. No idea about the cards though
I was literally going to buy some before I saw the rest of the video. Thank god I didn't. You sir have probably saved thousands of people from getting screwed over.
Have you considered trying to refine the metals from a catalytic converter? At one point people were stealing them so often the recycling places stopped taking them to combat it. Just found your channel and this seemed the best place to post it. Loving all your vids.
Maybe there is some gold, but not on the numbered cards but only on the ones with pictures? They looked a little different. I don´t know how deep the X-ray works. I would like to see if the gold leaf is picked up under the stack of cards or if one of the picture cards is treated with gold solving solutions. Great video Cody, can you give an update on the farm fire? Are the trees safe?

Wonder if the 'Certificate of Authenticity" was the only card plated in gold...
Da Hai Zhu if he included that card in the x-ray test then no. But no way of knowing if he had it in the pack or not.
I did test that card and got the same negative result.
I was thinking the same.
Same for box?
I was immediately suspicious when it said "Laboratory Report" but didn't have the name of a specific laboratory. The report # is probably identical for each pack -- a quick way to spot fakes.

The thought is that it was gold foil not gold plated, gold foil is essentially extremely thin sheets of gold that can be glued to a surface.
Not to mention it was $6.60ish for a deck of cards. That gives it away.
A lot of the time you start a process like this with electroless deposition of metal to deposit a thin seed layer. Then move on to electrodeposition. That's how you get those shiny chrome plated plastics.
You could deposit gold by RF sputtering
They might have been plated using the same method that they use to apply the metal layer to CDs.

Ideally thought I would recommend turning the cards to ash, and then treating the ash with a solution of AR and then testing that solution with stannous chloride to see if any precious metals are present. Or if you want to use your XRF just test the ashes prior to treating with AR.
As the cards are plastic, I imagine it would be rather messy trying to turn them to ash
No more difficult than converting black pack IC's to ash, low oxygen & high temperature.
The x-ray would have detected it if there was any gold on _any_ of the cards.
Incorrect, XRF's only detect what is on the surface or extremely minutely below the surface, also I mentioned to test the crown of the face cards as the only cards that was tested was the 6 of clubs. to test the entirety of a sample you would need to use another method like fire assay or ICP
You are correct, I'm definitely not qualified to run a $40k x-ray gun. Time to see if Amazon will cancel my order. ;)
Thank you for informing me/us.
Cody I've been watching your videos for like 2 hours strait until I finally got myself to go to sleep "new from codyslab"
Ooops Cody you left your delivery area in the video
doesnt really help too, only narrows it down to a pretty large area, i just checked
Yeah he basically describes where it is on his videos where he takes long distance videos across the valley.
One thing is, he doesn't actually live there, his father does, and the other thing is his dad would probably shoot anyone that came by looking to hang out with Cody ;)
I was curious one day and using only his video about getting water from town I was able to find his farm on Google maps *shrug*
pretty easy to find stuff on google maps in non-forested areas.
im pretty sure i once found the house of colin furze, based on a newspaper article and his video about building a shed
I brought the same pack of cards in a gift box for about £3 ($4) so I did doubt there was any gold involved, thanks for clearing that up!
Those five dislikes are the people who genuinely believed in the gold cards
crims 7n , Or the people who sell them to suckers.
liek me ;'(
I believe Cody found what 90's comics kids call "Marvel's Gold" All the rage during the 90's foil craze.
Can you do a series where you refine something starting from scratch? Like you take something that needs chemicals to refine but make those chemicals from scratch using only tools and no purchased chemicals aside from water.
I love these precious metal refining videos
Wouldn't it make more sense to add the sodium hydroxide before the hydrochloric acid?
Thats like asking if it makes more sense to multiply 2 X 3 than 3 X 2.
But doesn't the acid neutralize the NaOH before it has a chance to help the iodine dissolve into the water?
It's the Na ions that help it dissolve, and the acid doesn't touch those anyway.
Cody'sLab But if the reaction is between the sodium hydroxide and iodine then it would make sense to let that happen before adding the hydrochloric acid which will consume all the sodium hydroxide.
That gold leaf dissolving was beautiful!
coincidence that episode 25 involves playing cards, because there are 25 cards in the deck!
Are you dyslexic? There are 52 playing cards in a standard deck.
no trust me i counted, i found this deck of cards at the bottom of a septic tank, and i can semi-consistently count to 25.
... there are after Cody's done with it!
Enjoy all your videos. Wish I knew half the stuff you do when it comes to elements and chemical reactions.
Gold Fail more like it, hehe
I loved the last segment with the ticking clock. Got 60 Minutes vibes.
So let me get this right... you add HCl then NaOH and you think that... nevermind.
I thought the same thing... just add NaCl?
Meh, its all the same as far as the chemistry is concerned.
I sucked at chemistry so I wouldn't know if he was doing something wrong lol.
To be fair, HCl is the only acid you'll need 90% of the time
HCl + NaOH --> H20 + NaCl
He was destroying the acid he added that the process could use in order to create Na ions when he could have just added table salt (NaCl) to begin with.
cool shot with the time lapse dissolve and mechanical clock
Hey Cody,
I have watched this video like a hundred thousand times and I got to thinking..... Would you be interesting in revisiting the playing cards? The cheap ones of course and see if you can render the cards down and identify the metal they are made of... Perhaps if you could get the "plating" off of all of them and try to furnace it down to burn off the combustibles like the coating and such and see if you get some type of metal in the end? I miss these videos, I think it would be cool to see how to render all metals from ore. I live on a mountain and have a lot of rock to identify around the property.... You know what I think would also be neat, make a bar of fools gold, since the stuff turns to ash it would be a challenge I think.... Good excuse to make more crucibles and cupules. I don't know, like I said I miss the refining videos. If you could maybe use some tactics from Grants old videos and also make a sustainable forge for those of us that can't but they better stuff.
I finished graphic school in Offset Printing and these cards that aren't gold are just golden colored mass that is rich in some type of metal and on top of it we usually print a layer of coating.
I really liked having the clock under the timelapse!
I would really love to see a video in this series dedicated solely to iridium... aside from being a big challenge, it's also a super cool element in that basically 100% of it that you'll find anywhere near the earth's surface is guaranteed to have fallen from space after the earth cooled and solidified. So if you get a sample of it, you know it's pretty much pure meteorite atoms.
Watching gold dissolve was pretty satisfying.
thank you for reviving the series
I've used a vinyl wrap almost identical to the pattern on the box. I'd guess it's a 3M vinyl sheet with the carbon weave pattern in a gold color. No idea about the cards though
Thank god this series is back
I was literally going to buy some before I saw the rest of the video. Thank god I didn't. You sir have probably saved thousands of people from getting screwed over.
I like the use of the clock, it was a good idea.
Awesome video... Always love your videos Cody. 👍👍
I'm a jewelry designer and love these videos ;) thanks for educating us :)
what a lovely handheld detector! Now I need one to go playing on rocks
Polishing the surface to get rid of any painting might help reveal the base metal.
Have you considered trying to refine the metals from a catalytic converter? At one point people were stealing them so often the recycling places stopped taking them to combat it.
Just found your channel and this seemed the best place to post it. Loving all your vids.
Maybe there is some gold, but not on the numbered cards but only on the ones with pictures? They looked a little different. I don´t know how deep the X-ray works. I would like to see if the gold leaf is picked up under the stack of cards or if one of the picture cards is treated with gold solving solutions. Great video Cody, can you give an update on the farm fire? Are the trees safe?
