Athenian Silver Tetradrachm Value Guide

The Athenian Silver Tetradrachm, minted between 440-404 BC, served as the first international currency of the ancient world. These iconic 'Owls' funded the construction of the Parthenon and represent the height of the Athenian empire's economic and cultural influence.

What affects the value of Athenian Silver Tetradrachm?

• Centering of the strike, specifically ensuring Athena's crest and the owl's features are fully visible.
• The presence of 'test cuts' or countermarks which were historically used to verify silver purity but may lower modern collector value.
• Overall surface preservation and the level of detail remaining in the owl's feathers and Athena's helmet.
• Luster and toning, with original 'cabinet friction' or find-patina often preferred by ancient coin enthusiasts.

How to Identify Athenian Silver Tetradrachm?

• Look for the helmeted profile of the goddess Athena on the obverse side of the silver coin.
• Identify the standing owl, an olive sprig, and the Greek inscription 'AOE' on the reverse.
• Check for a deep 'incuse square' strike on the reverse, characteristic of the 5th-century BC minting process.
• Verify the material is high-purity silver, as these were trusted trade coins throughout the Mediterranean.
