This is a spintria (plural, spintriae). Some scholars have argued that spintriae were used to pay prostitutes, possibly for use in brothels. Since there were a lot of foreigners coming to the city that did not speak the language and most of the prostitutes were slaves captured from other places the coins made the transactions easy and efficient. One side of these coins showed what the buyer wanted and the other showed the amount of money to be paid for the act. There is no direct ancient evidence, however, to support the theory that spintriae were created as tokens for exchange in place of official coinage.
