Duit

The duit was the lowest denomination in the Dutch monetary system, and Holland's decision to strike copper coinage in the early seventeenth century reflected the commercial intensity of the province — small transactions in the booming Amsterdam market demanded enormous quantities of petty coin. Holland and West Friesland, though technically a single administrative unit, operated their mints with enough independence that die workmanship varied considerably between facilities, and examples from this short two-year window show meaningful variation in fabric and strike quality tied to specific mint output.
