From an American collection, ex Classical Numismatic Group 78, 14 May 2008, 2009.
This coin was struck from a particularly elegant pair of dies that were engraved by an artist termed, after Rizzo, the "maestro della foglia" because of the leaf that appears as part of the design. He worked at Leontinoi and at Katane, and was exceptionally gifted.
