Caligula, AE13 of Nysa-Scythopolis, Syria. Dated local year 103, AD 39-40. 1.95 g.

GAIOY KAICAROC, laureate head left.
NYCA CKYQOPOLEI, laureate head right.

RPC I 4830.1 (this coin); Barkay 8. 
Very rare.

Barkay notes the reverse head is laureate, and thus unlikely to be 
Dionysus, as RPC suggests. She suggests the head of Augustus, or Tiberius.
