Peep shows were popular establishments from the 1960s-1980s, where one would purchase tokens and then enter a room with a curtained window. You would then place a token into a slot and the curtain would open, revealing an erotic film or a live performance.
Some of these hard-to-find vintage tokens feature a zodiac sign on one side with a corresponding personality trait and sex position on the back. These particular tokens are COPPER-PLATED ZINC, the same material as modern US pennies.
Each token is slightly larger than a US quarter.
