"The janiform head has been identified as the Dioscuri, because the Fonteia gens came from Tusculum, the religious center of the cult of Castor and Pollux. The reverse depicts the arrival by sea of Telegonus' the son of Odysseus and Circe, and the mythological founder of Tusculum." ForumAncientCoins note Moneyer probably served as legate in 91 BC at the beginning of Civil war and was killed by rebels in Asculum.

This coin is currently consigned to Roma's E-sale 64. In his oration, Pro Fonteio, Cicero mentions that the Fonteii came originally from Tusculum, of which municipium it was one of the most distinguished families. The Fonteii claimed descent from Fontus, the son of Janus. A two-faced head appears on a coin of Gaius Fonteius, which Jean Foy Vaillant and others suppose to be the head of Fontus or Janus, in reference to this tradition. But as Janus is always represented in later times with a beard, Eckhel maintains that the two heads refer to the Dioscuri, who were worshipped at Tusculum with especial honours, and who may be regarded as the Di Penates of the gens. Michael Crawford likewise favours a depiction of the Dioscuri as they appear on other coins of the Fonteii. The galley on the reverse meanwhile is a reference to Telegonus, son of Ulysses and according to myth the founder of Tusculum
