Spintria

LINK quote [A spintria (plural, spintriae) is a Roman token, possibly for brothels, usually depicting sexual acts or symbols. They may have been used to pay prostitutes, who at times spoke a different language. While this is subject to argument, the numbers on them line up with known prices for Roman prostitutes (University of Queensland reference). Some theorize them gaming tokens, and they may have been produced for only a short period, probably in the 1st century A.D.].
