Kaisareia (AD 54-68) Drachm - Nero and Agrippina II

Nero and Agrippina II, 54-68 AD. AR Drachm (3.09g), struck 58-9 AD. NERO CLAVD DIV[I CLAVD F CAESAR AVG] GERMANI, laureate head of Nero right, countermark in right field / AGRIPPIN[A AVGVSTA] MATER AVGVSTI, draped bust of Agrippina II right, stacked KK behind head. Very rare: RPC lists only fifteen Caesarean drachms of Nero and Agrippina of all varieties, and only one, in BM, of this exact variety, with letters K K and Agrippina's unveiled head right on reverse. The K K probably stands for "Koinon of Cappadocia". The oddly shaped countermark on obverse, showing two objects resembling a minnow and a flounder, is apparently unpublished, since not mentioned in RPC or Howgego's book on countermarks. Fine+/VF.
