Ancient Greece captures the imagination like few other in history do. It was the time of the scholars, the home of great artists, classical philosophers, the birthplace of Western culture and Mythology. It was also for it's time one of the most stable and solvent economies in the known world. Coins minted in Athens were among the most trusted throughout the lands, carried by families, merchants, and soldiers. The head of Athena on one side, and her sacred emblem, the Owl, on the other, marked a coin as true silver, in its full weight.
The Athenian tetradrachm was nearly always welcome in trade because those trading knew that the coin was worth its face value. It was backed by a flourishing kingdom. The trust that others placed in the purity of the silver in the Athenian Owl tetradrachm served as a stabilizing force for the ancient world's economy.
