Silver.com is pleased to present a new free InfoGraphic teaching you how to avoid & detect for fake counterfeit Gold & Silver bullion products.
In recent years, the production of fake silver and gold bullion products has been on the rise.
At Silver.com… we want to educate the silver and gold buying community on how to avoid and detect fake bullion products.
If you are watching this video on RUclips, you can click on the link below to read this new free info graphic.
===========================================
There are two main types of fake bullion products threatening the market today.
Plated counterfeits are more common place… while hallowed out bars have been sold as recent as 2012 in New York’s famous diamond district.
===========================================
We’re going to show you some at home tests you can run to ensure your bullion is real.
===========================================
The Magnet Test
Silver and Gold bullion are diamagnetic, meaning that a strong magnet will not stick to them but you will see some resistance when a strong magnet slides across the surface of silver or gold bullion.
Notice the difference in speed between the magnet moving across the silver bar versus the paper booklet.

===========================================
The Ice Test
Silver is the best conductor of heat so we compared a real silver eagle versus a fake silver eagle by melting a piece of ice on them simultaneously.
Of all the tests we ran, this was probably the least definitive given that the copper in the fake coin is also a good conductor of heat.
===========================================
Ping Test
A ping test is performed simply by placing a bullion product on the tip of one’s finger and striking it like a tuning fork.
Please Note - 24K gold is too soft to work in a ping test. The shape of a bullion coin, round, or bar will directly affect it’s resonance and ping test ability.
===========================================
Acid Test
An acid test may help you identify if your bullion is real, just note that fake clad bullion coins will still test positive due to their thin precious metal venires.
Notice how on the fake coin on the left, the acid turns green die to the silver on the outer layer of the counterfeit coin.
Note too that acid tests leave burn marks on bullion items so this method of testing is certainly not for proof coin collectors.
===========================================
UltraSound & Caliper Test
The same technology used to map ocean floors and help administer prenatal care can also help you determine if your bullion is indeed wholly made of precious metals.
In this test we used a $135 ultrasonic thickness gauge tester which uses the speed of sound through silver to gives us an approximate thickness of the silver bullion bar.
We then used a $17 caliper to measure and cross verify our bullion bar’s thickness.

Caliper - amzn.com/B000GSLKIW
===========================================
Specific Gravity Weight Test
Perhaps the best most cost effective testing for bullion products is the specific gravity test. For this test you will need a digital scale, some distilled water, some string and a cup.
First you weigh the item in question.
Then add the cup with water and balance the scale back to zero.
Next fully immerse the item into the water without touching the sides or bottom of the cup, take down the measurement.
Finally divide the dry weight of the item with it’s water weight and you will get the item’s specific gravity.
Silver’s specific gravity is 10.49 Gold’s Specific Gravity is 19.32
===========================================
Be wary of silver and gold bullion deals too good to be true.
If you do buy bullion through ebay make sure to use protective third party payment systems like Paypal or credit cards.
===========================================
We suggest buying your bullion from trusted dealers who source their metals direct from the mints.
Make sure your trusted bullion dealer also tests and verifies all the products they may buy and sell from secondary market sources.

THANKS, By posting this video you have probably saved a lot of people from getting ripped off.
+Bob Brueckner we hope so. Thanks for you kind comment.

Pro trick : watch movies on Flixzone. I've been using it for watching lots of of movies recently.
@George Dakota Definitely, have been using Flixzone for years myself :D
You don't put acid on the item, you rub the item on a jewellers stone then test the stone, then wash off with soap and water when done.
Gold fill will pass that test. You need to check with quality electronic testers and specific gravity. Be thorough, there are several ways to verify elemental metals.
Great Video! Thanks
Probably the best video ever on silver
No need for your scales to be digital, or in any manner electronic. You can certainly use a small three-beam scale, especially if you pre-calibrate it with a set of good standards.
What a brilliant, informative upload 💯👌
Thanks Budd 👍
The best video I have ever seen!
Thank you.
This was extremely interesting. Loved the video
This is a really good video.
Thanks for informative video 🙏 🙏
Thank You SO MUCH!
Cheaters can still hollow the gold bar and put a non gold weight inside, until you scan the gold bar to see it's insides you cannot tell if this bar is gold inside too
Gold is very dense, so very heavy, other metal not. So measures size and weight, you'll know real or fake
@@ChainsawKLOBYK not if they put Tungsten. You'd happily have a Tungsten filled gold piece. Do research before commenting.
You scared the crap out of me. I cut open the Perth plastic tamper proof case and saw "VOID VOID VOID" appear as soon as I cut it open. My 1 oz gold bar is as you said, about the thickness of a regular quarter, weighs 480 grains on my scale, and is 1 5/8" tall x almost 1" wide. Now I see that my gold is definitely real gold. Yes, and the magnet test did show a slowing of the magnet across the surface.
thank you. Very well done. And here is a kicker back to you that I discovered while conducting your tests. I when I placed my coin up on a $20 bill, it fits President Jackson's head almost perfectly. hmmmm. thank you.
Outstanding video and should prove to be helpful to many in verifying their purchases.
thank you.
The Sound test is the milk! !!
LMAO
Thank you,then how will I test silver from raw form
Thanks.
I've bought from you several times.
Excellent guide
I go a bunch to see for myself how good they loomed
I don't know whether silver or gold is diamagnetic (most non magnetic metals are in fact either very weak ferro or diamagnetic not so little you need scientific tests to show it). HOWEVER it's NOT diamagnetics that make the magnet slide slowly down silver. It's magnetic braking due to eddy currents and the fact that silver is the metal that conducts electricity the best. In brass, lead etc. there's also generated eddy currents but since brass is a very poor conductor of electricity the braking is much less.
great info here
The specific gravity test was helpful.
Tungsten and gold has same specific gravity
You can buy an ounce of gold for $20. Usually it's just a slab of tungsten with a micron thick layer of gold electroplating LOL. The gold layer is so thin, you can still see the machining scratches on the tungsten xD
For silver I use the weight/size and rare earth methods.
Good day just ask if you buy paladium and platinum
thank you a lot you have saved so many innocent people
Great video thanks

Subbed
If you wanna test the conductivity use a multimeter, or place the coin over a metal surface so the heat can be dissipated thru it. the paper is working as a thin layer of isolator
what is the name of acid to test silver??
¿Sus productos lo pueden enviar a Perú ?/Your products can send it to Peru?
The last step(from 05:00) was genius!!! I have been trying to find a way for density test. Now I found it!
I like to point out that in order to be accurate. Step 3 is very crucial! You have to
1 completely submerge the coin and
2 the coin can NOT touch the bottom (or the side) of the container.
3 the string used should be as thin as possible. (You want the string to displace least amount of water)
How do you attach the string to the coin?
it could give an incorrect signal that the bar is pure. for eg. gold's and tungsten specific density is around the same around 19.3. there are chinese companies that openly sell gold bars filled with tungsten that will pass the specific gravity test - fyi.
i just thought i add a link to back my statement above. www.tungsten-alloy.com/gold-plated-tungsten-alloy-brick.html
Use 3 lb monofil line and water should be at 41°
Also ounces is more accurate than grams for most scales. And keep in mind for non pure metals, it might be real but the other metals might significantly change the specific gravity. So sterling silver coin might be 10.05. So not so helpful in that case as molybdenum is 10.2, not so far away from silver, 10.49. A sigma test would be better in those cases. For pure coins, thickness and specific gravity tests should work. Unfortunately, sigma and XRF tests are very expensive, but that may change soon for sigma.
great information
In Nellore district testing machines is here. Nellore. Chinnabazar. 524001.AP.india
So an American Gold Eagle would interact the same way with a neodymium magnet right?
Eddie: Yes, but not as strongly as silver.
Good video
Where to buy the acid for silver...?
Great video
Use nitric acid for testing
I have a maple leaf that doesn't quite ping the way my other coins do when I test tgen, but it passes the water gravity check... so anyone think I should get the acid to it?
MrKrzys01: Have you done the magnetic and weight tests?
There are lead alloys which have the same density as silver. You need to scan the piece (with ultrasound AND electrical conductivity).
I wear hearing aids..the striking technique is lost on me. Weighing is another problem. You to have a known weight to compare to. Beware of anyone weighing on their scale to show you that it weighs the correct amount. Also know the difference between tare weight and standard weight. If you don't know, learn!
Can copper filled silver ping?
XRF gun analyzer. its the best way to test precious medals. i wouldnt trust other.
A 20k piece of kit is only cost effective if you are a dealer. These are reasonable alternatives to sniff out fakes.
Can be beaten if the planting is more than 400nm thick.
I buy generic where it's just weight value. I can cut a bar half way across to prove its homogenous gold.
cool vid
Cheaters can still hollow the gold bar and put a non gold weight inside, until you scan the gold bar to see it's insides you cannot tell if this bar is gold inside too have
Where I can buy real silver dealer who can sent it to indonesia?
You can’t do the leaky test on paper. It has to be on an object that is room temp.
This is one of the best videos on this that I have seen. Would have been nice if the tests were ordered, whether by cost or effectiveness. Keep up the good work.
If they fill inside silver
I like the way the "weight test" is done! Smart move to not let the coin touch the bottom / sides of the cup.
Now im smart, i just need to get money somewhere and buy gold.
umm back in highschool you would just find its density by the water displacement technique
The problem with that is that tungsten is very close to gold in density: they both round off to 19.3g/cc. So a gold-plated tungsten bar can easily be passed off and will seem to be the same volume as pure gold. Silver is only 10.5g/cc so lots of cheap metals can substitute for it and still show the same density, by mixing the right alloys.
You can ping test pure 9999 or 99999 gold coins. they have a distinct frequency.
The Fisher Nitron XL used by pawn brokers and the mining industry will let you know definitively what metals your sample is comprised of.
Only of the top 0.3mm surface.
Awesome
does fake siver coins have milk spots on it?
Jack Handy: Real silver coins get "milk spots" sometimes so if you have one it doesn't always mean its a fake.
2:56 you got it backwards......lol
Acid? Really?
If you buy from the website are you safe?
VINO Mnzno depends on the site
No the acid turn green on fake one because of the copper present
The sound of silver is very distinct. That's how I discovered silver quarters and started collecting them as a cashier. I heard an odd sound I never heard from a coin, very loud, high pitched ring. Then I noticed the band all silver, it was from one customer and they kept coming to pay with silver quarters and I could always tell the difference.
Isn't there government sources to buy bullions? Those should always be legit, right?
No. Oddly the government will not sell directly to the public. You have to buy from suppliers.
Too bad the magnet drags on copper the same way as silver...
Is silver.com a legit company? seem a bit too good to be true.
Yes. They ar e reputable
Magnet test on JM, Royal Canadian Mint, Johnson Matthey, Perth, Asahi, Engelhard, RMC. This test proves that the bars people are interested in are just fine. Too many video's suggesting fakes are going around. Stick with the main name brands and you will not go wrong.

Ultrasonic way way more definitive than Specific Gravity test.
Depends on the thickness of the plating.
@@frankienorbertsteiner8167 Plating??? Are you serious? Do some research before opining please.
I have an 18.4 pound silver bar, it is spaniard from 1500's. How do i calculate a value if it holds significant historical value? It has passed all the tests...i didnt do the string suspension in water due to the string not being strong enough. I did not purchase it...i dug it up when treasure hunting on a 157 year old legend. Its much older than the legend but was first found before the civil war...the oxidation shows 500 years on its surface...but confederates cut it in half leaving 157 years of oxidation on the cut edge. It was casted in stone.
That is a pretty awesome story. story
In order to make the most of the historical part, you would need to provide some documentation to reasonably attest to the provenance of the tale. There are loads of fakes out there, so getting the documentation to justify your story is the key.
In all likelihood you would need to go through a reliable auction house to make the most out of the historical value. Start at the top by contacting Sotheby auction house and find out how much they charge in fees/ what percentage they take from the auction, what they would require in documentation, etc.
Good luck!
I would keep this to your self. Some agency or group will lay claim to your find. Delete your post or modify it. Good luck.
How to ruin your coins
Guy talking sounds like Johnny Knoxville
haha...sure does
Another way: shoot it like Demolition Ranch
Using paypal is not using a trusted payment system
I don't get why people place acid right on the silver. Scrape the coin then test the scrape; no weight is lost.
The 100% fool proof way is non-destructive, takes only seconds, but uses quite expensive equipment.
X-ray Fluorescence Spectrometer
Not cheap, but 100% certain. No faking possible.
That is false.
XRF testing proves only the surface materials down to 10 microns. Hollowed, homogeneous alloy, and "drilled-and-filled" bars need Ultrasound, Ultrasonic Thickness, and other testing for certainty.
Please don't spread false information about what is "100% certain" to guarantee buyers their Gold or Silver is real.
Great vid.
Why the music?
Also GET ON WITH IT!
kids in Africa could've eaten those ice cubes :(
I wish people would stop with the magnet test. Copper behaves the same way and is usually the metal coins are faked with. So it tells you nothing.
your water test result was off..
I confirmed your coins ping test with the bullion test app on my phone. :-)
Conterfeit ??? Really ??
Your slide/magnet test on the silver bar is a joke, because the resistance on the paper and plastic is completely different!
Doc Astro great try it on a real vs fake silver bar then - ruclips.net/video/NgSXg-WOEVY/видео.html
People, please stop buying silver, without demand no one will care about silver... and i can have all the pure silver to myself...
And do what with it? Stuff only has value if others want it too.
3:45 Co to miało być? Spier*oliłeś se gościu dobrą monetę!
So what it come's down to is, DON'T buy gold, silver or any precious metals from the USA.
I have no affiliation with them...MCM is a legit company.

You definitely didn’t need to ruin those coins with acid.
The unpleasant music, why? It's annoying. When you were in school or college have you heard any music during a lesson? No, because you need to concentrate when learning, the sound is distracting.

Don’t buy it in China
