Wow, someone disliked this video... maybe it's someone who sells fake silver on eBay.
+Master Of Coinage quite probably! The guy got his money back but the seller has relisted the items again!
great test backyard !!! I do these test often on anything that I suspect also !!!
+High Five Great to hear...If more people did this there would be a lot less disappointment and also less fakes as people would not get away with selling them!
Excellent video my friend! That is a very useful test! Thank you so much for sharing.
+Alexander R De Voogt thanks for watching!
Great informative video, I didn't know it was this easy to test..thank you.
+Ingrid Machado it really is very easy and a very useful tool to help avoid fakes!
The"poor mans tester" It is perfect. Thank you. Too bad for the customer. He should be known through Metals Mafia eh !
+Tomoko's Enterprize I dont want to name and shame people...not publicly though. Feel free to PM me.
No problem but the root cause must be found. We all HAVE TO adhere to our own strict standards. Looks like at this time it is one or the other is the culprit !
Tomoko's Enterprise The seller himself probably bought it from someone who told him it was 9.999 silver.
Do you have a list of the values / results that you SHOULD get for genuine coins of different metals (gold / silver / platinum etc) ?
I buy most of my silver on ebay and this is great to know. I always test with a magnet but I will always do this test now too just for the extra peace of mind. I'm relieved to report that all my stuff passed with flying colors... Phew!
Excellent video bud! This is a accurate fool proof simple non abrasive way to get purity results. I've done a video on it a long time ago using Zeke and HiHo pieces. The jolly roger is likeky melted down 90% coinage. Well done my friend, this should be all he needs to prove his case! 👍 Enjoy your vacation buddy!
+Silver Vessel I hope so, the seller quite clearly is either trying to con people or just doesn't know anything about silver! Thanks for commenting and have a great week my friend!
I agree with you ! I feel the test is as close as you can get
+Jon Hustad it is by far the best way to verify yourself quickly and easily!
to make sure it's even silver to begin with I love using the magnet sliding test and placing ice cubes on it and seeing if it melts as fast as a similar purity sized coin/bar. with the ice cube test you will notice the silver will get as cold as the ice, will fog up and will be covered in condensation even after you dry it whilst it tries to go back to room temperature.
+N .A both are very good tests to do, but as you saw here the magnet test would not signal a problem. The specific gravity test will, as I showed. Thanks for watching!
very good. little easier to do than I thought. looks like hardest part is tying that string.
+Silver Gator yes it is...hence why I pre-tied it off camera! Thanks for watching!
good demo, very informative, i have bought the precious metals verifier to test my silver, i couldn't find a UK or euro supplier so had to get it sent over from the US
+Benthe Boy That must have been expensive! But it is definatley the most reliable method. For those of us who dont have a verifier this specific gravity test is the next best thing!
Nice video friend. Its funny how this has come up in the past couple of days. A FB group was asking and I brought up this test as the best without a sigma machine plus a magnet. With those pieces you could acid test since just melt too. Someone did a video the other day too. Maybe all keep our eyes out might be a reason its come up a lot recently. Have a great holiday!
+Canadian Silver Saver Thanks CSS, in my opinion there is no better way to test without spending 1000's on a machine or damaging the item! Thanks for watching!
you have to wonder what they were thinking, like you said they either knew or are completely oblivious to the whole thing. i received a fake gold coin that Vessel and i performed a specific gravity test on it and it turned out to be either copper or iron. thanks for doing the community a great service and take care
+shiny packAGe I just wanted to share how easy it is to do this test at home. Its such a valuable thing to be able to do! Thanks for watching my friend!
I brought a silver ring from ebay stating sterling silver.
Did the gravity test came up 8.92g.
Seller has very good feedback.
Wow solid test I just bought some silver from an online page and I will definitely try this
Glad to have helped!
I do this with every coin or bullion I buy so many people ask how to test if its real and this is the one sure fire way to tell you exactly what you have and it's so easy
PSA. Learn abt metal properties and ways to test for those properties to authenticate your metal. Metal density can be dialed in/faked by alloying, or in the case of gold tungsten inserts. SG test will never know the difference between tungsten and gold. SG test is not foolproof.
Go to ' Basics For Testing Silver Gold....' by Silver Bullion TV. It's very informative and basically any one single property on your metal can be faked, except for Celerity(speed of sound of object). Also always cross-test your metals with at least 2 of those properties for peace of mind. My primary test which gives me 0.999 confidence. is the Celerity(ultrasonic) test using a $150 Ultrasonic Thickness Meter. P/s; the ultrasonic test is best for 0.999 gold/silver/platinum/palladium/copper/iron . . .
Wow thanks I'm trying this
Thank you very much.
+ThePwcj you are welcome!
Great topic!
Thanks, i think it is important to see how easy it is to test things!
thx for helping ppl out byb
+Golden Arms this public service announcement was brought to you by...thanks for watching my friend!
I was curious to learn how do you measure the volume. It is an easy approach but not quite sensitive. I guess if you could use graduated beakers and cylinders (laboratory glassware), to measure the volume/weight of displaced water, you should come up with more reliable data.
you could use a pencil to wrap the thread around to suspend the coin attach a bit of blue tack to stop it coming off. so its not moving around give you more accurate reading's. i did hear tungsten has same density as gold and this being used in some fakes now. so only true way is a pm verifier or a guess chemicals but this does work on most occasions. great video thx for sharing
+rox dude Thanks for the advice Rox, i think as a quick test to verify 999 or fake this dosen't have to be 100% accurate. I clearly demonstrated the difference between the 999 and the "925" and "900" so hopefully people will learn and be able and confident to test more!
Backyard Bullion indeed will definitely help and is easy to do really..... science is great...
I use this test regularly with eBay purchases. I have found a couple of silver coins and a 1887 half sovereign to be fake. I got my money back so I swear by this test.
+Chris George well this is the thing, buying through ebay is great, if you are not 100% convinced then you can send it back and get a refund! Thanks for watching and commenting!
Really interesting and I particularly like how you used available inexpensive items to help with the test (pop bottle and floss) however I wouldn't be myself if I didn't call something out; why didn't you just suspend the object from a pencil or something as the chance for inaccuracy by just holding the item from the floss is quite great.
For a more accurate test, use cold water. 50 F or less. If you put and ice cube in the water, they will be near perfect.
so with this simple test it seems like a sigma machine is not needed? Is that accurate?
I have some homemade silver I want to test and I know those machines like specific coins/bars to test. Not oddly shaped things. 🙂 Great video and saved to my PM folder!
It's a federal offense to misrepresent metal purity in the U.S. If the seller is doing this on a regular basis, he could be in big trouble.
+Silver Gem it is also a crime here in the UK. The buyer got his money back but the seller has relisted the items! Very bad indeed!
Tell him to report that the seller has relisted the item, and Ebay will ban the seller.
I really liked this test. This is the second video of the similar but same tests. This shows accuracy. The question is.....if one ounce size is the same of all with these measurements. Would different sizes have the same results. Thank you
Thanks, appreciate the feedback on the video. It works on all different sizes of silver and gold.

You could always take them to a place with an XRF analyser
+Platinum Skies Yeah...but I dont know anyone with one! And they aint cheapd
That’s awesome
I like to use the magnet and weigh but I wouldn't have even touched that "silver" if it looked like that the buyer best have got got that at a very very good price but thanks for sharing your methods and have a good time away my friend
+Ag D so the thing with this is that as you saw the magnet test showed it to be all OK! The specific gravity test shows otherwise! I also would not have bought this silver, apart from the fact it looks piss poor in its pouring it just doesnt look like 999 silver. Miss stamping it suggests the seller either is deliberately trying to con people or he knows very little about silver! Thanks for watching and commenting!
Backyard Bullion I think I found the seller on ebay and the one picture still does not do the piece any justice and at a premium price
+Ag D yep, I knew who it was when I saw it...looks like a shoddy piece of work to be honest!
Very very nice !
Thanks!
Barber quarter came in at 9.91, do you think it's legit?
great test BB. What would be the target specific gravity numbers for 999, 925 and 90%?
999 = 10.49, .925 = 10.36, .900 = 10.31, .800 = 10.17

Thanks bud!
+Silver Bear it does depend on the alloy as to the exact result. It becomes quite hard to be precice when it is not 999 pr 925. But as an indication of whether something is 999 or fake there is no more accurate way!
Specific gravity values. These are the results you SHOULD get if your metal is genuine.
www.farm.net/~mason/materials/specific-gravity.html
You are misusing the word density with regards to specific gravity. You also need to factor in atomic weight. For example, lead has a high atomic weight, even higher than gold, but yet gold is 80% heavier than lead. That is because lead is not very dense. That is why it is so soft. Osmium has a lower atomic weight than gold but is denser and heavier than gold.
Does this technique work with gold as well?
Yes it certainly does.

I am guessing that the round is 90.0, because many people melt down pre-1965 scrap silver. Thanks for the video, it was really helpful!
+Rhett Carlson quite possibly yes! Thanks for watching and commenting!
Would borax take out the impurities and get it closer to 999?
could there be air bubbles trapped inside of an amateur pour like these?
In theory, yes there could be. It's quite unlikely though and even with that possibility it would not explain the other issues that are showing on these pieces.

The ultrasonic thickness meter detected air bubbles in some of the gold bars they featured on the video.
A 999 stamp doesn't mean anything, anybody can buy 999 punches from ebay etc. The buyer should have checked to see if it had full hallmarks.
I totally agree, that is why hallmarking is so important!
Too many ads for a thumbs up!

I question e-bays commitment when one considers the fraudulent activity of some sellers who misrepresent their Silver bullion and rounds etc. There are a number of sellers at the moment selling unequivocally fake silver rounds, eg: 2015 silver Koala's.............Despite repeatedly notifying e-bay, the sellers continues to sell these pieces as genuine and their feedback continues to be glowing.
It appears a lot of punters do not do their research after procuring their silver purchases and take for granted if the sellers feedback is good then their products must be too. Although i have bought plenty from e-bay over the years, the volume of fake silver on their pages is genuinely increasing. it appears e-bays commitment to stop or take action against this type of seller is less than pro-active as they try to make us believe.
It is imperative (regardless who we purchase silver from(, it is checked over to ensure it's the genuine article. Videos like this are crucial to stop us being ripped off. We work for our money and when we spend it we should get what we have pay for. Carry on the good work........great informative video.
