Watch List notes:

THRACO-MACEDONIAN TRIBES, Derrones. Circa 480-465 BC. Dodekadrachm (Silver, 32 mm, 40.06 g). Male driver, wearing petasos and robes, seated to left on a throne-like chair, mounted on a two-wheeled ox-cart moving slowly to left, holding the reins in his left hand and a curious goad in his raised right; above the oxen, crested Corinthian helmet to left. Rev. Triskeles to right, almost totally effaced by die wear, on plain field. Svoronos, Hell. Prim., 17 and pl. II, 2-3 (same obverse die). Very rare. With an obverse that is very boldly struck from fresh dies, and beautifully toned. Reverse struck from a very worn die, otherwise, about extremely fine.
From a European collection presumably acquired in the 1920s.
