Ex NAC sale 39, 2007, Feirstein part I, 39. The mint at Athens produced an extraordinary variety of denominations of its silver coinage, though the only one it struck in large quantities was the tetradrachm, which became something of a universal currency in the Greek world. Among the "owl" coinages, the didrachm was unusual, though in the earliest phase of Athenian coinage, the period of its "heraldic coinage" (Wappenmünzen), it was in fact the standard denomination. It is rather surprising the didrachm was not continued by Athens in quantity, for at about 8.6 grams it weighed the same as the staters of Corinth. Stylistically and technically the "owl" didrachms are of great interest because the reverse takes the standard composition of the series and adds a remarkable twist–an artistic simulation of the "incuse square" that can be observed as a byproduct of the striking process on all other Athenian owls from the archaic and Classical periods. This unusual feature earmarks the Athens didrachm as something more than just a rarity, but an artistic and technical experiment at a mint that otherwise is renowned for its draconian uniformity. In the usual case of an Athenian silver coin, the incuse square is created at the time of striking by the excess metal cupping around the edges of the square reverse die. The reverse dies used to strike the didrachms, however, were round, not square, and on examples with particularly broad planchets the full circumference of the die is revealed. For the didrachms, the engravers cut a square into the circular die, and within that square they engraved the traditional design. And yet there is another innovation to consider: the olive sprig that on the standard issue of Athens is placed wholly within the field of the square die is here shown overlapping the faux "incuse square" and the raised plane surface of the circular die, with the result being that one leaf is in the square and the other rests upon the ledge of the circular field.
