Here is a scan of the $100 slot token apparently used at Binions in Las Vegas before Harrahs bought them. It is thicker than most other 100 tokens used recently (about 2 mm). It's weight leads me to believe it's silver covered with gold. I've been unable to find a strict definition of the word "24 KT. Gold Inlay" marked on the token. The token has been used, and the edge shows a silver color where it is worn. Google search results mostly refer to jewelry making where gold inlay means gold has been pressed or pounded into recesses during fabrication.

The token has a USM, United Silver Mint mintmark. Janice's list shows this mint as closed but I don't have a date.

This token appears in the Nevada Gaming Chip / Token Tracking database with the notation "no documentation" and with no date for either approval or destruction.

Other unusual characteristics of this token include:

Some recessed areas on each side of the token appear to be filled with black (enamel?).

There is a stamped 4-digit number on one side, apparently a serial number.

Has anyone seen serialized slot tokens, or tokens with enameling done to them (other than the decorated ones available to the hobby recently as samples)?

Dan, you are welcome to this scan for the token website if you need it.
