Helmeted head of Athena left / Helmeted head of Athena right; monogram to upper right; all in dotted square within incuse square. Cf. Zapiti & Michaelidou 2 (same obv. die, rev. type facing); cf.

Near VF, lightly toned, obverse die very worn, test cut on reverse. Extremely rare, unpublished in the standard references.

This coin is obverse die linked to an issue of Sidqmelek with the facing head Athena reverse type. However, those coins also have the name of the king on the reverse, which is not present on this issue. Thus, due to the die wear on the obverse, it is possible that this may be a coin of an unknown king that succeeded him.
