I'm new to the silver world and have bought around 50 ounces so far mostly from the EU mint. I have just bought some 2 oz yale queens beast coins from Amazon as they were a good price. Now I have started wondering as most probably do if all my silver is real. I have bought some digital calipers, some scales and a magnet to carry out the basic tests. The magnet has not arrived yet however the scales and calipers have.
Testing the weight the coins seem fine and testing the diameter there spot on however with the thickness they are only 5.56 mm but the official thickness is 6mm.
So after the long winded opening my question is are the thickness a sign they may be fake? Also they dont seem to ping test very well but I dont know if that's due to them being thicker than my other 1 oz coins.
