onkia/hexas of Akragas, 450 BC ca.

Calciati 9    9.33 g     Numismatica Ars Classica AG, Auction 13 8th October 1998 no. 255
                         Ex Antikenmuseum Basel und Sammlung Ludwig no. 255


This is the only member of the second cast series. It has a round shape and is without a
mark of value. Westermark lists 10 exemplars. Calciati I lists 3 more. The flan is
truncated-conical. The metal is poor, the coins were cast in pairs.
The weight is ca. 9 g. 

Westermark proposes the possibility that the heavy onkia (Calciati 8) may be associated
with this round "hexas" and "... that these two coins form a separate group based on a heavier standard of ca 54 g independent of the cone shaped coins of a somewhat lighter weight (litra ca 45 g)." (Ulla Westermark: The Fifth Century Bronze Coinage of Akragas
in Atti del VI Convegno del Centro Internazionale di Studi Numismatici - 
Napoli 17-22 Aprile 1977, pp 3-25)
