Essential Tools for Counterfeit Detection

Young Numismatists Exchange | JordaNumismatics

These are the few tools I myself use to prevent myself from purchasing any counterfeit coins. I have attached my own photo of a counterfeit coin I own to strengthen my stand.

1. Precision Scale
Preferable to a precision of 0.01 grams. If the weight of the coin if off by more than 0.1G(In UNC condition without wear), be wary about a counterfeit.
2. Neodymium Magnet
A neodymium magnet will be the key of testing any silver coins. Paired with a jeweler's loupe, it will detect most nickel/copper nickel counterfeits.
3. Jeweler's Loupe
A jeweler's loupe will detect most plated coins. Look for places where the plating has worn off and exposed the inner material. Also look for cast counterfeits and small details that counterfeit coins sometimes miss.

Thank you for your time reading this and I hope i have helped any beginner collector.If I missed anything kindly leave it in the comments and I will add it in, and of course citing your name. Have a great day ahead:)

Excellent information. Thanks for sharing!

Thank you all for your inputs! Another Note: I decided not to edit the post (i'm too lazy) as people could easily read the comments.

A caliper or micrometer is another helpful tool to use in conjunction with the aforementioned items - try to learn the diameters of your coins too, as another means of thwarting counterfeiters. And as you gain knowledge and experience over the years from looking at so many coins, you learn to use your "gut" also. If a deal seems too good to be true, then it probably is - trust your gut!

These are great ideas!

I'd say you have the 3 basic tools. I'd also recommend reading about counterfeit detection and looking at as many graded coins as you can. This will ensure they are genuine. Well done!
