They were novelty matching coins Head-tail flippers,nudes or clothed people with or with out advertising, with animals again with or with out advertising. Non- pictorial types with just words,political flippers, stock market and topical flippers. And yours which can be anywhere form late 60's to present.
There is also modern adult arcade tokens that are flippers as this example They use the tokens as they can raise prices on the peep shows and vid players without replacing the insert in the coin ops. Plus there is the hope that people would buy some to give to friends.

There also is the male versions.

ebay.
moderns are less .25 to $3.00
