Counterfeit Buffalo Silver 1 oz Rounds on eBay

This is a thread building on the counterfeit Morgan dollar thread in the US Coin forum.

The same seller is selling counterfeit Buffalo silver 1 oz rounds here:
https://ebay.com/itm/silver-round-1-ounce-silver-buffalo-round-FREE-SHIPPING/182937893302?hash=item2a97f2b9b6:g:sWsAAOSwNWxaFbk2

I know they are counterfeit ... because I bought two (and have already started the return process).

The round has the following properties:
Diameter = 40.0 mm
Thickness = 3.0 mm
Dry weight = 24.515 g
Displacement weight = 3.93 g
Specific gravity = 7.23

The specific gravity leads me to believe it may be copper mixed with tin and/or zinc that has been plated with silver. At least it gave me an excuse to built a crude apparatus to measure specific gravity.

    If you own a sigma tester, I'm sure it can tell you too! I know member @Weiss has one. A friend nearby has one and I've used it, very fast and accurate, easy to use as well

    Many members on this forum that now it cannot fit in my signature. Please ask for entire list.

    I looked into a Sigma tester and they look great. They are just too spendy for what little use I would have for one.

    @astrorat ... I agree ... great tool, but my usage just won't justify the expense. Cheers, RickO

    I use a Sigma PMV. Worth the cost.

    I use a rare earth magnet. A quick, inexpensive screening test. Harbor Frieght has a tube of the small button type for a good price.

    The most money I made are on coins I haven't sold.

    Got quoins?

    I don't buy enough "questionable" or "suspicious" bullion to justify the $600+ expense. If I owned a shop or was a purchaser of "vintage" bullion ... I would be all over it! Then again, I do like gadgets ... :)

    I own one. Only need one bad purchase to justify the cost. I highly recommend getting one !!! :)

    I was thinking about getting a Sigma PMV, but even the basic model is not foolproof in counterfeit detection.
