good to hear. Cheers, it's sad that fake coin exist, but I'm scared about this problem becoming really huge for casascius, I hope the community can find a decent solution, maybe a blockchain based one. Why not grade them all, and put an "unique" chip on the graded plastic, with anchored proof of authencity on the bitcoin blockchain? Chip could own the PK that made the anchor or something like that

Obviously its not easy tech, but there is not so many coin especially very valuable ones
