I have what is marked on the edge as "ONE OZ. .999 FINE SILVER." It is a Chumash Casino strike with a picture of an Indian riding a horse and the text, "CRAZY HORSE" on top and "SOVEREIGN SILVER" on bottom of the face of the coin. The back of the coin says "Chumash Casino" in the middle, "POKER ROOM" on top, "SANTA YNEZ" and "CALIFORNIA" on the left and right sides, respectively, and "KING OF THE HILL 1998" on the bottom.

Despite about an hour of internet research, I have yet to find mention of this strike, let alone another example photographed or assigned any kind of value, rarity, or desirability by anyone.

Anyone have any insights on this piece? I would love to hear it. Thanks so much!
