Can You Find ‘Secret’ Dime Marker?

There are no secrets to coin authentication. All it takes is a stereo microscope and either the diagnostics of a genuine specimen or access to known genuine coins for a back-and-forth comparison. Oh, and I’ll add the dedication that comes with hundreds of hours of studying the surfaces of genuine coins with both eyes at the same time using the stereo microscope at perhaps 7X to 20X. All the methods of examination you should use with a hand lens apply to the scope.
