|Remarks=This is a coin of considerable numismatic importance! The Elean hemidrachm was struck soon after the coinage of Olympia began, but utilized a slightly earlier issue of the Arcadian League as a flan. While a number of Elean coins are known overstruck on issues from other mints, especially Aegina but sometimes from Boeotia, most of the undertypes are rarely closely datable. This piece is almost certainly R.T. Williams, The Confederate Coinage of the Arcadians in the Fifth Century B.C. ANSNNM 155 (1965), 86, ascribed to the mint of Tegea and struck c. 477-468. The goose-necked back of Zeus’ throne is visible above the eagle’s upper wing on the obverse, and the diagnostic lower profile of the head of the Arcadian goddess (Williams die R. 53) is visible below the thunderbolt on the reverse
