So I was given some fake ASE about 6 weeks ago to see how they compared to the real thing as ASE are the bulk of what I tend to buy, I normally stick to current year from well-known companies but I do occasionally like to buy from their circulated/random year inventory.

There are various ways to test suspect silver. A common way is with an acid testing kit if you are not worried about preserving numismatic value, you can use a strong magnet (however this only rules out magnetic fakes, every fake I’ve personally encountered is non-magnetic) or you can buy a more expensive testing device like the Precious Metal Verifier made by Sigma Metalytics.
