Denier of Charlemagne

Charlemagne's denier was the backbone of his monetary reforms, standardizing weights and purity across his sprawling empire to curb the chaos of earlier coinage.

Weighing about 1.7 grams of silver, it featured a simple cross on the obverse and the king's name or monogram on the reverse, making it easy to identify amid the counterfeiters of the day. Minted in places like Paris and Dorestad, these coins flowed through markets from the Rhine to the Pyrenees. No one knows the exact mintage figures; records from that era are as scarce as honest merchants.

The denier's design drew from Roman traditions, yet it innovated by enforcing a consistent fineness that predecessors often ignored. If you're picturing a grand portrait, think again—these were functional, not flamboyant.

Some claim these coins carried mystical powers; I've handled enough to say that's nonsense. They were tools of trade, plain and simple.
