Oord

The Friesian oord occupied an awkward position in the Dutch monetary system — a provincial copper piece whose exchange rate against silver shifted repeatedly as the States of Friesland quarreled with the generality over small-change policy throughout the Thirty Years' War period. Copper coinage of this type was chronically overproduced by several provinces simultaneously, flooding local markets and driving repeated official attempts at demonetization.

Survivors in any condition above heavily worn are genuinely scarce; these circulated hard in a region where small copper was the daily transaction coin for most of the working population.
