Doesn't have a year on it anywhere...

But it's says "proof" and "999 Fine Silver" in a plastic case and there is a little round white sticker on it that says $50.00

On one side in the center it has a $ sign with Harrah's across it and says Harrah's. Reno and lake Tahoe, redeemable by player only along the rim.

On the opposite side- center- is a Big 1 with Harrah's across it and says Harrah's Reno and Lake Tahoe Nevada, dollar gaming token around the edge.

I got another one from Harrah's that says 1965 silver on a little white sticker, and another sticker that says $40.00 and this one has the same description as above coin but also says "BUCK SLOT MACHINE" on it.

So what are they worth now?
