If you are interested, APMEX (American Precious Metals Exchange), sells random .999 Silver Strikes for $20.96 each (credit price; you can get them a bit cheaper if paying by check or wire). By "random" I mean that you don't get to pick and choose; they will send you something from their stock. They note that "Items may be beautiful, ugly, tarnished, or even a hidden treasure, but all are guaranteed .999 fine Silver! Pieces may or may not display weight" however I've ordered several and they are all in capsules so any issues are with the capsule itself not the strike--so far anyway! I have received a nice variety including Luxor, Bally's, Bill's Casino, etc.

Search for "gaming tokens" on their website. I don't know if this is something they sell continually or as they have them available. Other precious metal retailers may sell them too.
