After a bit of research, I think it's an even rarer find -- the previously unknown 1909-O trial strike! The product of a highly secretive effort by Mint employees to preserve the New Orleans mint as a going concern, this issue was doomed when the presses were set up by the same bozos who set them incorrectly for Morgan dollars. You see the result -- a strike so weak that it couldn't even be issued for circulation. Oh, well, it was worth a try.
I don’t think it’s a capped die, but... Just like a walk on the beach, big or small, we look at them all.
Looks to me like a copper round that Columbus lost while coming ashore yesterday. It's super that you found it. Thanks for sharing.
Looks to me like it could be anything you want it to be. Especially now that 'Legalize It' has taken hold virtually countrywide.
