You have to couple the slide test with size and weight. Sure copper is diamagnetic, but a coin made out of it will be significantly off on either size or weight. (your fake one is noticeably bigger) They will also slide down a magnetic slide at different rates so having a reference is important.
Actually the fake one is the same diameter its just lighter. But I made this video because I had people telling me they just use a magnet... nothing else.
@@SilverSeeker but it’s perfectly sound logic though. If it’s made a copper, it will be either 86% lighter, or 17% larger, or a mix between those two. I guess this highlights that likely no single test is accurate and requires a minimum of two unique forms of measurement to determine validity. Anyway, I still appreciated your video. Thank you.
Yes, it is a good screening test. And if the coin has a copper core, it either weighs less than an authentic or has different dimensions because Cu is not as dense as Ag.
This is new to me. I have seen brokers just use a magnet to see if something that should not be magnetic, sticks to a magnet, but have only seen them use other testing methods to verify precious metals and purity.
Silver is a good thermal conductor. So if you put an ice cube on top of your silver item, then the ice cube will start to melt quickly. An ice cube placed on silver will melt quicker than on iron and a little quicker than on copper.
I actually built a full rare earth magnet slide when I first got into PMs - and was quickly disillusioned when much of my common house change slid just as slowly as silver did.
That's because all US coins except for 35%, 40%, and 90% silver coins, 1943 steel pennies, and post-82 zinc pennies have a high percentage, above 75%, of copper and therefore diamagnetic.
Bring a rare earth magnet, a scale, and a ruler (a sound test app is also good). You will also need the information of the coin that you are purchasing (weight and measurements). A fake may pass one of the tests, but not all of them
What was the weight and dimensions of the Fake Silver coin that passed the magnet test? Surely the dimensions (using calipers) and the weight would differ enough?
Unlike gold, silver has a specific gravity that is fakeable. Lead is denser than silver, copper, tin, and zinc are lighter. So there's a ratio where an alloy of copper and lead that has the same density as silver. But is that alloy diamagnetic?
Just getting into this topic, but I already figured out that the the 925 and magnet tests can be bypassed/faked. The problem is that people just repeat what they've read online and never take time to do research on the basics. But as always, I'm always the exception and not the norm. To answer your question, yes. Going back to the "basics" copper is diamagnetic while tin and zinc are not magnetic.
I thought the "pocket pinger" has that built-in plastic extrusion to strike the coin so you don't need to use any external stick, pen, whatever. Or...is there a reason you don't use the built-in striker? edited to fix typo edited to be more precise
OWWW.....that hurt ....lol great video, you did a perfect job explaining how this works. Definately another option for checking your silver. Thanks for sharing. SALUTE>
I have counterfeit non-silver coins that give the same ping as silver coins. The solution is to use a balance and the ramp test as metals with other densities will weigh more or less.
My father in law left my kids each a couple silver morgans when he passed. All fake. 2 of them were in the right weight range while the other 2 were way light. All failed the ping test 😌. It was enough to get us all into collecting coins tho. Great video!
The lenz effect is much stronger with silver than the copper so silver will slide much slower. So even tho they are both diamagnetic the ailve is more diamagnetic
Testing the mass of a coin is highly reliable, very inexpensive, and repeatable. A jeweler's scale, an appropriately sized vessel filled with water, dental floss or thread, and a calculator are all that are required. It does take a little more time to perform and requires getting your coin wet, but I consider this test a valuable tool in my verification "toolkit".
Pure or coin silver will make a fairly drastic eddy current test. To do so space a rosette of rare earth magnets spaced about 2x the target coin thickness. A silver coin will act like it is falling through molasses. So will other metals like copper, but silver is a bit slower. It is a quick test to test for plated. Another way to use a magnet is that for metals of similar density it requires a nickel layer that will attract a small re magnet to the coin. 🤓

Is that ping tool any better than simply using silver dollar A to hit the test coin with & see if it sounds the same a hitting a real silver dollar with the same silver A ?
Pinger is quicker but the end result is the same. Before the pinger I used to balance the coin on my finger and hit it with a wood pencil so that it didn't damage the coin, but I would drop them alot.
Use multiple but Weight + Magnet isn't enough, I'd at least at the ring test to that also. Additionally if it's a government issue like an Eagle I'd also check the size and thickness with a pair of calipers.
is there any metal or combo of metals that would pass both the slide and the weight test, in one coin? If not, that may be a nice cheap and easy combo for people to test their silver.
Its so bad I won't buy except from a reputable dealer, which I don't have in my area so I will order from SD or other bullion dealer. Its not worth getting ripped off.
just weigh the coins and measure them. If the copper coin is the same size it will be much lighter than 31 grams. Silver eagles should be ~ 3 mm thick, very easy to measure with a pair of calipers
This video is mislabeled I think it should say "why you shouldn't trust the silver magnet test on BULLION" this won't work on a necklace or a ring or something the sure fire way is call around to jewelry or pawn stores and ask if they have one of those handheld xray testers they tell you the exact percentages of the metal content in them....most good jewelry and pawn stores have them now!
I don't know why I watch this video I guess I find it entertaining I bought a sigma metaletics detector when I first got into silver. Best thing I ever did I bought a fake Platinum coin and I got a refund I paid like $900
I'm going to get a magnet for testing ! I already have the Pocket Pinger. Have a metric/inch ruler. Need to get a good scale for measuring the weight of gold and silver coins. Any suggestions on a good scale ?
doing these test and the specific gravity test with water and a scale seems like it would be more that sufficient to prove the quality of the silver and even the % silver. So I guess no one needs a sigma device. 🙂
Sigma provides speed AND accuracy. Specific gravity test is slow and messy so if you're testing a lot of items at once the Sigma is definitely useful. But is it NEEDED? No
I bought five 2023 Silver Eagles from a seller in China. The coins shipped from Kentucky. They passed the size , weight and magnetic slide tests and they are real silver. The weight test was spot on. Always test silver three or four ways . Spend a little to have peace of mind.

The magnet test is good if used with all the other tests.
Yes. You should do all tests to se if it's fake or real.
Yes, it is a good screening test. And if the coin has a copper core, it either weighs less than an authentic or has different dimensions because Cu is not as dense as Ag.
Yes it should be 1 of many many. Never definative, niether is a sigma pmv alone, or ping sound etc Only thing is an xray thats dependable 100%.
Thankyou for the explanations. Most of us out in the economy don't know anything about silver ...
This is new to me. I have seen brokers just use a magnet to see if something that should not be magnetic, sticks to a magnet, but have only seen them use other testing methods to verify precious metals and purity.
Great info man I remember learning this from you a long time ago very helpful
Thanks so much for watching!
What about sterling coins, does it have a enough silver to do the same thing on the magnet? Curious and thanks for any answers.
Sterling silver is .925 or 92.5% silver. Yes it will do the same thing with a magnet.
@@johnsumner2987 Thank you sir
@@guystumm9387 No problem
I do the ‘Silver Sound’ Test on circulating coins. That is how I discovered my first Silver coin: 1966 80% Silver Canadian Quarter.
Yep, with just a little practice you can hear junk silver being jingled all the way across a room.
Is the crown mint considered a reputable dealer?
Silver is a good thermal conductor. So if you put an ice cube on top of your silver item, then the ice cube will start to melt quickly. An ice cube placed on silver will melt quicker than on iron and a little quicker than on copper.
I also do the ping test. BTW, today I got my "pre order" of the T2 2021 Silver Eagles from Monument Metals.
Woot!
Awesome educational video. Thanks for doing this!
Oooh, great video, thanks!
what about silver bars, does the ping test work with bars too.?
I actually built a full rare earth magnet slide when I first got into PMs - and was quickly disillusioned when much of my common house change slid just as slowly as silver did.
Me too
Same
The best test is the ‘Sliver Sound’ Test, has a higher pitch than the other clad coins
your angle was off then. As he showed the magnet does have an effect. You need strong enough magnet as well.
That's because all US coins except for 35%, 40%, and 90% silver coins, 1943 steel pennies, and post-82 zinc pennies have a high percentage, above 75%, of copper and therefore diamagnetic.
Bring a rare earth magnet, a scale, and a ruler (a sound test app is also good). You will also need the information of the coin that you are purchasing (weight and measurements). A fake may pass one of the tests, but not all of them
dont "solely" rely on this test, correct. i personally like doing a calipers diameter test + a scale, and a ping test.
What was the weight and dimensions of the Fake Silver coin that passed the magnet test?
Surely the dimensions (using calipers) and the weight would differ enough?
I LOVE my Pocket Coin Pinger! Thank you Seeker for your AWESOME channel!
Glad you like it! Thanks so much!
Don't have a pocket pinger, but I just ping the coin with another coin
Just curious did the copper coin weigh correctly?
It's always good to use multiple types of tests
This is a huge help - thanks. I tended to rely on the neodymium test only - so this helps put my mind at rest!
I just got one of them pocket ping test at my fisrt coin show the other week works great
Where can i buy a magnet like you are showing in your video
You can buy one on Ebay.
Good vid. Thanks for the pinger link. Ordered a pinger and a fake coin. Cheers!
I bought a Pocket pinger! Cait wait. Thank you 😎✌️🌻🌻
Unlike gold, silver has a specific gravity that is fakeable. Lead is denser than silver, copper, tin, and zinc are lighter. So there's a ratio where an alloy of copper and lead that has the same density as silver. But is that alloy diamagnetic?

To answer your question, yes. Going back to the "basics" copper is diamagnetic while tin and zinc are not magnetic.
@@beethao9380 But the alloy? Is it possible to create an alloy that will match specific gravity and the magnet test?
I like using the rare earth magnet test along with a scale. I always verify my bullion through my LCS though.
I just ordered one through your link. Thanks for your videos.
Always good info!! Thanks!!
Thanks for watching!
Great info Seeker!!
Didn't get notified about this video. Glad I found it. 👍👍👍👍👍

I prefer to just strike it with a stick, but yes that is there also.
does the ping tester work on random very old silver rounds?
Very interesting! 😊👍
great info as always thank you
Thank You!
OWWW.....that hurt ....lol great video, you did a perfect job explaining how this works. Definately another option for checking your silver. Thanks for sharing. SALUTE>
Thanks for watching!
does the pocket pinger work on "junk silver", how about old dirty coins?
Great content! 👍
Great video with excellent info.. thanks
Will a One oz. Rectangle ping the same ?
It will still sound like Silver but no it wouldn't sound the same as an eagle. Thickness diameter shape all change the sound.
How about the specific gravity test
🤘👍Great video!
Very interesting!! Thanks!!!
So what was the coin that failed the magnet test made of ?
How can you test a silver bar??
Interesting, thanks for sharing!
I have counterfeit non-silver coins that give the same ping as silver coins. The solution is to use a balance and the ramp test as metals with other densities will weigh more or less.
What about the u test? 1986 to 2007 has a u in United but 2008 to present has the serif in the United?
Wow, I learned something today. Thank You Sir.
"Ping" test is the way to go ... . ..
Great Info!!
How would I test silver bars?
Ordered one brother
Very informative , thanx Silver Seeker
Very good tutorial. Thank you
What size is that fishing magnet?
My father in law left my kids each a couple silver morgans when he passed. All fake. 2 of them were in the right weight range while the other 2 were way light. All failed the ping test 😌. It was enough to get us all into collecting coins tho. Great video!
LOL. ..finger test doesn't feel good. But seriously this is a good video for info
LOL thanks so much!
DO you have a link to the bullion test ap you use
but cooper are slightly lighter and the ping is different.
Yo where do I find a magnet like that
Great info. Thank you!
The lenz effect is much stronger with silver than the copper so silver will slide much slower. So even tho they are both diamagnetic the ailve is more diamagnetic
It's stronger but not "much" stronger. If you don't know what you're looking for you'll get fooled quick
Thanks for the details.

I've covered specific gravity on the channel more than once, no worries there. :)
So the same test a Greek king payed for to see if his crown was pure gold is still in use
Did U create/invent the pocket pinger ?

Pinger is quicker but the end result is the same. Before the pinger I used to balance the coin on my finger and hit it with a wood pencil so that it didn't damage the coin, but I would drop them alot.
Isn't this just because of the conductivity and magnetic induction, has nothing to do with the diamagnetism.
Ok, we if we do weight and magnet test, am I good? Or do I need something more?
Use multiple but Weight + Magnet isn't enough, I'd at least at the ring test to that also. Additionally if it's a government issue like an Eagle I'd also check the size and thickness with a pair of calipers.
4:46 LOL
My ping app is buggy Freezing up on me
is there any metal or combo of metals that would pass both the slide and the weight test, in one coin? If not, that may be a nice cheap and easy combo for people to test their silver.
Nailed it
Right
Its so bad I won't buy except from a reputable dealer, which I don't have in my area so I will order from SD or other bullion dealer. Its not worth getting ripped off.

More4 great useful info..
Great informations.
i always test it with magnet and ping test.
Thanks for the info. Wondering if the ping test works well on 90% Constitutional silver as well as .999 pure?
Good stuff...
Love that!
Did notice the fake spun rather than slid. I trust my magnet
Real ones spin also just depends on where you place it kn the magnet
@4:45 LOL!!!
Brass does the same thing.
Well brass is 2/3rds copper so yep :)

Just mine your own ore and cast your own bars! Duh!
I'm going to get a magnet for testing !
I already have the Pocket Pinger.
Have a metric/inch ruler.
Need to get a good scale for measuring the weight of gold and silver coins.
Any suggestions on a good scale ?
Magnet test is just one in your tool belt..
magnet, ping, weight, dimensions. four easy non destructive tests.
doing these test and the specific gravity test with water and a scale seems like it would be more that sufficient to prove the quality of the silver and even the % silver. So I guess no one needs a sigma device. 🙂
Sigma provides speed AND accuracy. Specific gravity test is slow and messy so if you're testing a lot of items at once the Sigma is definitely useful. But is it NEEDED? No
@@SilverSeeker agreed but for $1000+ for a real tester I'll take the messy water way and put that money towards gold and silver. 👍🏻 Good stuff!
Here's another easy one. Place a tissue directly over the silver, if the silver appears white in color it's probably real.
I bought five 2023 Silver Eagles from a seller in China. The coins shipped from Kentucky. They passed the size , weight and magnetic slide tests and they are real silver. The weight test was spot on. Always test silver three or four ways . Spend a little to have peace of mind.
