Watch List notes:

MACEDON. Terone. Circa 490-460 BC. Diobol (?) (Silver, 10.5 mm, 0.90 g). Oinochoe with handle to right. Rev. Quadripartite incuse square. Hardwick - (for an anepigrapic twelfth-stater weighing 1.30 g, see pl. 29, 7). For comparable pieces, see: Berk BBS 209, 2019, 195 (0.95 g, but handle on the left); G. Hirsch Nachf. 293, 2013, 2166 (1.13 g); Roma e2, 2013, 139 (1.07 g, but oddly termed a tetrobol and given the wrong references); CNG e258, 2011, 74 (1.01 g, termed a 1/12 stater). An attractive and clear little coin, nicely toned. Good very fine.
From the "Collection sans Pareille" of Ancient Greek Fractions, ex Münzen und Medaillen FPL 461, November/December 1983, 20.

Is this coin from Terone? The types say yes but the weight says no: it is not a fractional stater (it would have to be a 5/96, which is absurd), and while the weight would be vaguely right for a diobol, Terone did not issue any, at least according to Hardwick. But since the fabric is Macedonian, what else can it be?
