A Clashed Seleucid Obverse Die of Philip I Philadelphus

Abstract

This article publishes two Seleucid tetradrachms of Philip I Philadelphus struck with the same
unusual obverse die. It is argued that peculiar raised and incuse features on the obverses are
the result of a die-clashing error during minting. Two additional clashed Seleucid dies suggest
that this sort of error often occurred in times of crisis when the mints were forced to quickly
produce coins to meet sudden high demand.
