Vespasian Æ22, 9.42g Uncertain mint, Undated Obv: ΑΥΤΟΚΡΑΤΩΡ ΟΥƐϹ[ ] ΚΑΙϹΑΡ ϹƐΒΑϹΤΟϹ; Head of Vespasian, laureate, l. Rev: ΤΙΤΟϹ ΚΑΙ ΔΟΜΙΤΙΑΝΟϹ; Bare heads of Titus and Domitian facing one another RPC 2812 (0 spec.). Acquired from eBay, June 2021. A true mystery coin. Struck at some point during Vespasian's reign, this rare dynastic issue's origins remains elusive. RPC's footnote concerning the type: 'The editors of the SNG Schweiz II tentatively attributed these coins to Crete, which seems unlikely. A Cicilian mint is a possibility.' There are not enough surviving specimens for findspots to help determine a region of circulation. As is, we are left only with style to go by. With that being said, somewhere in Asia Minor is a good bet. The reverse design was fairly popular throughout the region and the style is similar to several cities which were producing coins during Vespasian's reign. The bevelled edge flan may also be a clue, perhaps pointing to a mint closer to Syria or Commagene. The dynastic type itself hints that this issue was struck earlier rather than later in the reign. Perhaps in the future, archaeology will provide the clues needed to solve this intriguing mystery. Please post your mystery coins.
