A remarkably fine example of this coinage, with an attractive, smooth olive-brown patina and a particularly majestic head of Zeus Ammon of the best early Hellenistic style. Good extremely fine.

Ptolemaic Egypt had a very carefully controlled coinage system: gold and silver issues were primarily used for external purposes, while a whole series of bronze coins, including some of large size and heavy weight, as this one, were used within Egypt itself. The bronzes took the place of lower value silver coins and initially contained metal that was roughly equivalent to their tariffed value. That they circulated widely is clear: the vast majority are worn, often heavily so; as a result, very well preserved examples, as this one, are actually very rare. Interestingly enough, the heavy weight of these coins lent themselves to be used in imaginative ways: at least one example of an ancient 'vending machine' is known from Egypt. In one sanctuary worshippers could put the required number of coins into a slot and their weight would activate a dispenser of holy water!!
