an off-white one (different than the white one) and two or three versions of metallic ones. One silver and two gold (you seem to have one).

This according to the Collectors Guide to Nevada Promotional Tokens, by The Coin Company and Washoe Antiques.

Evidently there are 5 different types (variations) of these tokens.

Type 1 - "RENO" above left-Indian logo dropping 6 coins.

Type 2 - "RENO" above left-Indian logo dropping 5 coins.

Type 3 - "CASINO BAR" on reverse.

Type 4 - "RENO" between legs - tight lettering in "CAL-NEVA".

Type 5 - Drilled "RENO" between legs - spread lettering in "CAL-NEVA".

Nice acquisition!
