Take a look at your 1966 Diamond Jim's Nevada Club dollar, Jim. There are several varieties. If it doesn't have a FM mintmark, it was made by Osborne. Several varieties on the Osborne token. Look at the alignment of OBV/REV to see if it's Coin Aligned or Medal aligned. Also look for doubling of the date and some of the letters.

Coin aligned and doubled characters may be worth several times what the FM's are. See details in Janice's list or on Dan's web site. Still not an extremely rare token, but could be something a serious collector might pay $25 or so for.

It's fun to look for the early sixties Nevada tokens because there were so many attempts to make them and several different mints before FM finally won. Even different metals on several of the early ones to find out which the customer liked best.
