Watch List notes:

IONIA, Uncertain. Circa 600-550 BC. EL Trite – Third Stater (12mm, 4.69 g). Lydo-Milesian standard. Facing head of lion or panther within triangular incuse [on a raised area] / Two square punches with raised lines within. Weidauer 158-9; SNG von Aulock –; Boston MFA –; Traité I 28. In NGC encapsulation 5872643-006, graded Ch VF, Strike: 3/5, Surface: 4/5. Very rare denomination, much rarer than the hekte and hemihekte.

This trite is part of an electrum series consisting of staters, trites, hektes, hemihektes, and twenty-fourth staters (cf. Weidauer 156-65). Miletos and Samos have been proposed as the possible mint, though the former is now discounted by R. Hilbert's die study of the electrum issues of that mint.
