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.

They should be available from the mint in collector’s tins, and available in circulation from eBay and similar.

They’re great to use as board game coins; much nicer than plastic chits.
