SICILY, Syracuse. Hieron I. 478-466 BC. AR Tetradrachm (23mm, 17.28 g, 6h). Struck circa 475-470 BC. Charioteer driving quadriga right; above, Nike flying right, crowning horses / Diademed head of Arethousa right; four dolphins around. Boehringer Series XI, 240–1 var. (V108/R– [unlisted rev. die]); HGC 2, 1307; Randazzo 242 (same rev. die). VF, toned, die breaks on reverse. Apparently unique for die combination.

From the J. Eric Engstrom Collection, purchased from Frederick S. Knobloch, 1965-8. Ex Burgess Collection, Tulsa, OK.

The die combination of this coin is previously unknown, and the reverse die was unattested until the analysis of the Randazzo hoard identified it on a single example.
