Entire Process of Melting Down Silver Coins, Refining, and Testing to 0.999 Purity

- This is a step by step process of how to melt down your silver using items you can find around your house. The two special items you will need (for the complete process) are Nitric Acid (preferred 68-71%) and a way to melt it (propane furnace, electric furnace, makeshift furnace depending on how much you are melting). If you have the infamous 40% silver half dollars, this is one way you can go about making them into a pure silver bar. I melted down mostly "no date" 90% silver coins, 40% silver halves, a few Canadian silver coins I had come across in my roll hunting over the years, and a worn silver money clip. In the past I purify and melt down 0.925 sterling silver I find at estate sales as well. Lets see how much we can get, and how pure it will be!
I see a lot of people just melting it down and dumping into casting. It looks like crap with discoloration and fire scale. Yours is very shiny and fairly smooth
I love almost every silver refining video I watch. I love silver so much more than gold and I don't know why!
Bc silver is cheap compared to gold if u could afford gold ud be into gold
Me too. Really strange.
I guess you like tarnish? oops I meant "patina" LOL...compared to gold silver is kinda obnoxious ...try putting $10k silver in your safe deposit box for instance ...whereas $10k gold? You can carry in one front pocket and close your hand around it
@@dougiequick1 I dont care what it looks like I'm into money and silver flips faster and easier then gold.
Me to I’m addicted and I love it !
You could claim the copper also,just switch te copper bar for a iron/steel bar,and the copper cements out as the silver did
That bar sort of resembles a kitKat bar. break me off a piece of that silver bar. Nice job.
I would love to do this to some 35% nickels, I’m just a little sketched out working with nitric acid. And those fumes look like something out of a ww1 trench
Agreed I have one silver that I would love to refine too
They are 😬
93% sulfuric acid will do the job! it takes quite a bit longer but will extract the silver! then there is a process to change it from silver sul to silver chl then back to metallic silver. Not saying Sulfuric acid is any safer but it will do the job if Nitric is not available. Its all in Hoke's Book
Or a WW2 Jewish summer camp
This is mind blowing. Real
Money
Very informative and well presented, Thanks for the video !
I'd like to see this done with before and after weighing of the results along with consideration of the cost of acid as other individuals who have done this under lab conditions have noted that without performing additional chemical treatment of the acid that you're losing a certain amount of weight.
As such, how's about a controlled experiment - take ten ounces of 40% silver and see how close you get to four ounces of fine silver along with acid costs to determine what the premium is for obtaining fine silver in this manner?
I think I would also recommend doing it with 90% to see if maybe one is superior to the other.
What do you think about breaking down the silver first - get a good pair of bolt cutters and say, quarter or eighth the coins to expose more surface area to the acid and thus possibly generating a faster and/or more efficient reaction?
Finally, for the filters, do you simply stuff a bunch into a crucible to burn them away and recover trapped silver or place them directly in acid to remove it?
Really cool video, man!
Where did you buy the furnace?
coolest shit I've seen in a while
Wow! You mustn't get to see much!
@@OneTequilaTwoTequila nope. too busy overseas protecting people like you in the states.
Very cool! Would you say it's worth it to buy the "bulk 90% 500$ coins silver" bags on bullion websites and melt it down like that? Where do you get your coins? This definitely seems like a cool hobby to get into, I love the idea of smelting fun little things as well as melting all the aluminum cans I use lol.
I would say only if you get them for far less than spot (like a garage sale or from coin roll hunting) since the cost of the nitric acid will offset some of that.
I have a full size 25 pound metal forge that I use for copper, aluminum, and brass - I typically only use it in the winter as it is QUITE HOT.
Personally, I don't think it's smart to melt 90% US coins. Because they "self-assay" and trade just as they are. If you melt down junk silver coins into a bar, nobody knows what that bar is composed of. That means it's worth LESS than what the original coins were worth. And now, you maybe are thinking about getting involved with nitric acid and those fumes. Those fumes are fiendishly toxic, they can kill you and a splash of acid can blind you. Nitric isn't cheap. Neither is the PPE you MUST have if you are going to deal with it. Then, you need the furnace or forge, whichever you choose. I don't consider it a casual undertaking.
Hi mate new at this. Please tell whats the best gas musk to buy thats help my protection of the dangerous gasses . Thank u.
Could you use urea to neutralize the excess nitric before adding the copper for the ion displacement? Just a thought
Yes you could. Just not using a crazy amount of nitric would be better though.
A good video, perhaps just add a little bit of math so you can calculate how much nitric acid you need, and avoid using up your copper.
Very informative video 📹
Do you live in va
What happens to the other parts of the comes such as the nickel, copper and whatever else is in the coins? Does that all dissolve or will parts of the comes still b there? Cuz I've got portions of coins left that haven't dissolved and I feel that I'm just throwing nitric at it.
Would this process work with silver contacts out of breakers and stuff
NIce Vid! But I was confused at the end on your terminology of the number of "nines". I have always used the number past the decimal as how many nines there are ie. 99.99 would be 2 nines.. the whole number is implied. No biggie though, thanks for the vid!
99.9 = 3 nines (0.999 pure)
99.99 = 4 nines (0.9999 pure)
That is how it has always been explained to me.
@@ScottHD Looking into it more, it seems the difference is if you look at it as a percentage or a decimal fraction.I'm just used to the decimal fraction notation. So I was wrong to think the whole number was implied. Learn something new everyday!
Forget the 9's the decimals 0.0% are calculated in tenth such as 0.1 is one-tenth or 10 cents move the decimal by adding a number in front of it 1.0 = (100%) or behind and it becomes 0.01 which is one-one-hundredth 1/100th of a percent or one-cent. So when you see 1.0 that is 100% of the whole which could be a variable of the whole pending the decimal placement.
1.00 is 100% or 10 dimes or 100 pennies of the whole in this case the purity of the silver.
$99.99 is like 10,000% how many dimes are there in a one-hundred-dollar bill?
Since decimal is calculated in tenth 0.1 = 1/10th, or 10-cents, therefore, there are 10,000 dimes in a $100 dollar bill because 1.0 or 1.00 is 100 percent which takes 10 dimes to equal 100% therefore, 1.5 is actually 150% or $1.50.
0.999 is not as pure as 0.9999 but you are only talking 0.001% or 0.0001% of a difference, take a penny and cut it up into 10 pieces, 100 pcs or 1,000pcs.
Now take one piece from the 100pcs and mix it into 1.oz of silver and you will have 0,999 percent pure, take one piece from the 1,000pcs and mix it in with 1.oz of silver and you will have 0.9999 percent pure. Take 10 pieces from the 10pcs and mix it in with one oz of silver then you are getting closer to sterling and coin silver.
A 1oz 90% silver coin has about .77% of silver or about 3/4 of an oz of silver the rest is other metals such as nickel and copper so if you melt it down and remove those other metals from a 1oz 90% silver coin you will have about .75% of silver left from the 1.oz coin.
Simply (1.0 is 100%) (.1 is 10% or 1/10th of a percent and that is what decimals work on) (.001 is 1/100th of a percent) then you have (1/1,000th of percent .0001) so if you have .999 you are 1/100th off of being pure, more junk mental or .9999 1/1000th of a percent of being pure less junk mental. Because when you start going to the right of the decimal smaller of the amount .000000001 and when you start going to the left of the decimal 1,000,000.00 the greater the amount.
So you will need 0.009 + 0.001 to equal 0.01% which is the difference of one-grain of sand or salt versus 10 grains of sand or salt of impurities mixed in 1.oz of silver. Really too small to worry about unless you plan to buy a million ounces.
Nice video and you sound like Tom Hanks
Wow, thanks haha
Thanks, that was very informative and the process relatively simple.
How much silver/other weight did you start with? How efficient was your recovery?
Awesome!
Thanks!
people that buy worn out Constitutional Silver coins for the silver content dont realize its not worth the trouble melting it down. if you ask me the silver in the coins is useless.but it still makes them more valuable and collectable.
Depends on what you do with the silver.
The coins themselves are trusted and so will be easy to unload and at a predictable rate, plus, if you anticipate a situation where you'll use them as currency, they'll also be easily and readily accepted for trade.
On the other hand, if you can turn the coins into bars or rounds of sufficient quality then you can get a premium for them.
Since Scott is simply producing generic, unmarked and uncertified bars then he's likely losing value due to the bars needing to be tested and thus having a low trust level. The lack of trust of the value of his bars also means that unloading them will be a challenge unless he has established a reputation since most people who deal with silver will either refuse to purchase them or purchase them below premium.
@@seanfoltz7645 just my opinion. but i wouldn't buy silver coins just for the silver content .if you wanted to invest in silver why wouldn't you buy bullion and not have to mess with the whole refining process. i know the silver value will be more than face value but i have no interest in refining metals. but i still liked the video
@@ridgerunner7980 Most folks don't refine government silver when they purchase it as bullion for the reasons I mentioned above - a pre-65 Kennedy is 90% silver so it's definitely worth $9.20 spot as of this posting while the ingot or nugget you refine it down to is worth less since the person purchasing it has only your word to go by.
As such, I agree - I wouldn't melt it just to turn it into bullion either.
@@seanfoltz7645 i love old silver coins in good condition , right now i'm looking at a 1895 half dollar thinking someone could have had this in their pocket while riding a horse into town then going into a saloon a buying a shot of whisky with it.
@@ridgerunner7980 I like to think about the historical people - 1895 means that Teddy Roosevelt could have bought a shot with it.
Kinda wanna melt mines but kinda wanna keep em
Is there a way to get a second verification on the .999 for resale purposes?
As well, I saw the weighed bag, but how much “face value” was actually in the bag?
Great video!!
Horrible video you never showed putting the chemicals in
You really should try to rinse and wash the silver directly in the glass, without using the coffee filters and in the end vaporizing a bunch of water. You can put the rinse water out of the glass into the filter, but don't give all the silver into the filter. Makes live a bit easier imo.
do not stir nitric with wood
I havent seen a video yet with this thorough of explanation for melting junk/constitutional. If I am correct all yours were 40% correct not 90%? Yet you were still able to get to 99.9% how awesome. I have strongly considered going through 35% War Nickles and trying this. Everyone seems hesitate to buy 35% and local dealers ive spoken with dont trade it. So if I have any why not give it a go. However it may be more trouble than its worth and perhaps need to just stick to the 40 and 90s.
It was a mix of 40% halves, 35% nickels, and a few 90% dimes.
...and a silver belt buckle was in one of the batches too
I think the issue with a lower percentage (35%-40%) silver is that you will be using nitric acid to dissolve the (mostly) copper in those coins to get the silver. So it is using the nitric (expensive) - more of it - to get the desired result.
Hands down the best video for beginners ! Great job !
Glad it was helpful!
Really nice furnace, really nice crucible and mold. And a sigma. And a coffee pot, coffee filters, metal pans, and wooden spoon. Eek. You can buy glass beakers, nonreactive dishes and glass stir rods all for less than $75. And lose a lot less silver along the way.
I have since done that!
Tom Hanks???
you dont need chemicals to retrieve the copper, just add some iron
What was the paper in the coffee pot when you started
♥♥. Didn't notice you mentioning SAFETY equipment - gloves, possibly a thick rubber apron, and, SAFETY GOGGLES.
Whenever working with chemicals (nitric acid in this case), and heat, safety is the No. 1 priority (especially your eyesight).
Agreed!
one question...could this process work with 10% silver coins? if so... whats going to happen with the left overs (nickel)
If the silver coin has dark or colored toning, will this process eliminate those colors from the silver?
If you have coins that are 50 silver and 50% how do you get both mentals out?
*Great video mate. I was always curious to see silver coin melts.*
Thanks 👍
That was cool I want to do the same thing some day
Really cool! Thanks for the video
I find this to be the best descriptive silver refining video on youtube
May I suggest watching sreetips here on TH-cam. Almost the same process but explains the science a little better imo
Sweet, new sub
That was amazing man thanks for breaking it down! Subscribed for sure 😁
Thanks!
Very cool!! Thanks!!
I would like to talk to you more about this, I'm in Texas too, close to Dallas how can I contact you?
Where do u get reasonable priced nitric acid
Chemical companies - two things - have to pick them up in person as the shipping for hazardous materials is expensive and second, buying a lot of it at a time. I'm fortunate to live close to Dallas, TX where I can check both of those options.
What good does it do you to test your stuff at home when you still have to pay someone to test it before you can sell it and they're say so it was all that really matters at the end of the day am I wrong?
I dissolved my silver coins and at the bottom of beaker it looks as if there is some silver that precipitated to a grey powder. Looks like I already put copper in it but I haven't. Do I add that to my silver after I get it precipitated?
Love the simplicity of this video
R U OUT OF UR FUNKING MIND?
Whts the value after melting silver coins???
What was the weight of the silver scrap you put in?
How much nitric acid
Very nice. Good video
vacum filtering would help tremendously, got a bunch. of 40% stuff I need to do this with. You don't try to recover the copper at all?
Excellent video
Is this a cost efficient method?
I would say only if you got the silver really cheap and/or you have a lot of it.
aren't the coins more valuable as coins?
@Paul Yall no. refining the silver makes it worth more? I can see the fun of it, but not profit, and you're destroying a work of art.
That’s AUsome that you pulled 4- 9’s
