The City Mint is the only authorized facility for the striking of Greyhawk Gold (Wheels), Silver (Nobles), and Copper (Commoners). It takes in raw bullion from the Cairn Hills and the Abbor-Alz, purifies it in massive subterranean furnaces, and presses it into the standardized coinage that drives trade across the central Flanaess. It also serves as the official Weight and Measure authority, where merchants can bring foreign coins—like those from Nyrond or the Iron League—to be assayed and exchanged for local currency. This is a windowless fortress of seamless, reinforced granite blocks, bound together by lead-poured joints and layered with thin sheets of anti-magic copper. It is a squat, imposing square structure that looks more like a military bunker than a place of commerce.
