Only 10 sets made in Lucite, encased by the Mint.
Gaming turned down the $1 and $5 values in pure silver and the actual tokens released were a silver looking alloy
The actual $25's released were pure silver though.
A 'small number' of loose $1's and $5's had already been delivered, and while not put into play, they got out somehow. Thats all I know.
Obviously, had I been suggesting only 10 of each token ever existed in any form, I think I would have been looking for a bit more $$ for them
