Watch List notes:

ASIA MINOR, Uncertain. 3rd century BC. AR Obol (12mm, 0.93 g, 1h). Laureate head of Zeus right / Shield and sword; ΔIOΣ to left. Leu Numismatik Web Auction 17, lot 1242 var. (rev. type reversed); Nomos Obolos 19, lot 301 var. (same); Nomos Obolos 17, lot 104 var. (same); Roma E-Sale 61, lot 213 var. (same). Porous. VF. Extremely rare.

Some of the prior sales attributed this issue to the Bosporan king Leukon II, based on the use of the reverse symbols on his issues. However, these symbols appear elsewhere, and Zeus does not appear on Leukon's coinage, so an attribution to that king remains speculative.
