Yes, the US Mint sells all of the coins in the American Innovation set to the public. Previous years’ coins can still be bought if they are not sold out.
Not an American but I wouldn't mind having some of these. Actually, coin collecting is a pretty neat hobby, especially for commemorative coins which depict a story like these. I wouldn't go in it for their possible future financial value though.
I used to be a coin-collector as a kid. Kinda outgrew the hobby as I grew older. But I still love new/old/unusual coins (among other things). I think I might get my hands on some of these.
I wonder if these coins are available for purchase by the general public? anybody know?
