Pelanor
Pelanor was the currency used in Sparta during the rule of Lycurgus. It was supposedly said to that just as it was red hot, it was quenched in vinegar, thus rendering the product unusable for any other purpose than money. This, according to Plutarch in his book "Parallel Lives", reduced the amount of robbery and theft, for who would want to steal money that is practically worthless in small amounts. Archaeological Evidence. Some sources attest that pelanors have been recovered in Spartan archaeological sites.
