Something You Probably Didn't Know About The Basic Sigma Metalytics PMV!! #test #finance #silver

In this video, I explain the reason why you should NOT test your 90% silver using the Basic Sigma Metalytics Precious Metals Verifier. This Basic machine only tests the resistivity of a metal and in this case, 90% silver and Clad coins have a similar resistivity, giving you a false positive.

Instead, you may want to use a ping tester to authenticate your 90% silver coins or conduct a specific gravity test with some simple tools like a bottle of water, an inexpensive precision balance, and floss. Below are the links where you can purchase a decent balance and a ping tester. Thanks for watching!

Sigmas are great for bullion, but nothing besides specific gravity tests (which damages the coin) is better than a scale in combination with calipers. That’s old school, but it works well. It should also be noted if you’re going to do a specific gravity test, use distilled water. Great video!

Very informative video SGT. Thanks for putting it out there!

The clad composition was designed on purpose to reflect eddy current similarly. This was done to appease casinos, so they didnt have to modify their coin validators as silver coins were going to be phased out.

I discovered the same thing & I was searching for videos to see if anyone else is having the same issue. I too was able to put a simple 1991 quarter & it passed. False positive! Thanks!

Thank you Sgt for the info, great video brother

I caught about half of what you said… tinnitus 😢

Thank you for sharing and explaining the gravity test!

Community exclusive 👍I've never seen a specific gravity test on precious metals. Lovely Psalm on your logo

Great video. As a rule, I never accept one single test to validate a coin. Weight, diameter and thickness, then test on the sigma. If there are any flags, a gravity test. Personally, Im not a fan of 90% silver and dont stack any. Recently bought a 1800s gold coin that I couldnt verify on the Sigma. Ended up doing a scratch test to confirm its 22k gold to validate it. Because f that, I wont even deal with old gold anymore.

This is a brilliant video SGT. I learned a lot. Thanks for sharing. Time for me to dip my silvers LOL 😂

Thank you for sharing this. However, this issue is specific to 90% silver. I’m not a collector. I stack primarily 1 oz gold bars, 1 oz silver eagles, maples and buffalo rounds and bars. For these products there is no problem.

Good job we all appreciate the video Thanks

Specific gravity test is really the only one you need and it's easy and cheap; you just need a scale, a plastic cup, and some string. Just pat dry with a soft cloth if you're worried about damaging the coin. Where the Sigma excels is detecting tungsten-filled gold, as that will pass the specific gravity test but the Sigma will catch it because the conductivity will be different. It's also okay with .999 bullion, but can confuse copper and silver-plated copper with sterling and 90% silver.

Wow, I never would have guessed that. Very helpful video!

[WorldMoneyWins]

Great advice! I have the Sigma Pro version because of this very issue.
If I had it to do over again, I would probably have bought the Pro Mini and saved a bunch of money and been able to access more features through the app.

Hopefully a Sigma will be in my Christmas stocking 🙏

[weeklybullion]

Excellent video, SGT. I don’t have a lot of 90%, but the specific gravity test is a winner!

Hiya S.G.T. BLESSINGS visiting from VENUZ MARTINEZ great work....left my like!✅

Great detective work SGT, appreciate you sharing this information, happy 4th of July. Cheers from the land down under Peter J 🕵‍♂👋😂🗽🇦🇺 🐨🦘👍

Great vid, as usual! I still don’t have a Sig, but someday.
