The Tetradrachm denomination
A tetradrachm is an ancient greek coin denomination worth four drachms - 24 obols - and weighing around 17.5 grammes Attic standard or 15.6 grammes Rhodian standard.

Tetradrachms on the Attic standard became the de-facto standard for trade and for large payments, and the denomination was used well into Roman times.

The most famous tetradrachm is the Athenian 'Owl'. In Roman times, provincial tetradrachms were usually struck in debased silver or billon.
