Hello All, Thanks for looking. I picked up this coin in a local online auction. So the standard 1889 10c weighs 2.33 grams and is 1mm thick.
Mine is 3.43 grams and is 2mm thick. It is none metallic, and passes the silver ice test.
Google says its not possible to have a thicker and heaver coin and that it is counterfeit.
Any thoughts? Thank you.
