GREECE: George I, 1863-1913, 10 lepta, 1912, Karamitsos-139a, ESSAI type without privy marks, PCGS graded AU58, R. Notably rare; while the present type is not designated as an essai by the SCWC, both Karamitsos and Divo indicate that these "no privy marks" issues were struck as unindicated essais that frequently entered into circulation. Finest graded at PCGS.
