Civic money of the Seleucid east
Seleucid and Greco-Bactrian cities struck bronze under royal authority for local circulation: municipal denominations, often countermarked and re-tariffed, changing types far more freely than the silver did. Because these coins never travelled far, findspots make them unusually good evidence for regional economies.
Parthian and Elymaean bronzes continue the pattern, with degraded Greek legends that turn progressively into ornament — a visible record of Greek literacy fading from the Iranian plateau across three centuries.
Surfaces and conservation
Bronze is the most fragile material in an ancient cabinet. A stable dark green or brown patina protects the metal; powdery light-green spots are active bronze disease, a chloride corrosion cycle that will eat the coin and can spread to neighbours in the same tray.
Isolate any affected coin immediately, keep humidity low, and have treatment done by a conservator rather than by scraping. Never strip patina to reveal bare metal: the surface detail sits in the patina, and a stripped bronze loses both history and value.
