Watch List notes:

SELEUKID EMPIRE. Seleukos II Kallinikos. 246-225 BC. AR Tetradrachm (30mm, 16.89 g). Uncertain mint, perhaps Nisibis. Diademed head right / Apollo standing left, testing arrow and leaning on tall tripod; uncertain monogram to outer right. Cf. SC 748c (Nisibis); HGC 9, 303. Toned, surface marks. Near VF. Possibly an unrecorded variant – references do not seem to record an issue with only a control symbol/monogram to the outer right and none to the left.
