Price PO (2) 15 = Prokesch-Osten, "Suite des monnaies inédites d'or et d'argent d' Alexander le Grand," NZ 3 (1871), 15 (Phaestos in Crete). Extremely rare and unusual. Price was not able to see a single example of this type in order to confirm its existence, so the type was not included in the corpus. Struck on a very tight flan, otherwise, very fine.
