Now I'm aware of at least three different coins being counterfeited: Casascius, Lealana, and Bitcoin Specie.
Joseph congrats on your success with your silver coin. Very happy for you. Aloha.
Mahalo, smoothie.
The brass silver-plated pieces look pretty shoddy, so I hope no one gets fooled. Also look like they may be molded rather than struck, wrong size, wrong weight, wrong year, wrong in so many ways.
I'm more concerned over the high-value pieces that are being copied such as yours and Mike's. Someone could get badly harmed, they are infringing copyrights at minimum which probably is enough for eBay to drop them.
