Charles V standardized Low Countries coinage through the monetary ordinances of 1539 and 1548, folding the previously fragmented county coinages into a more unified imperial system. Holland's penning issues from this window were struck at Dordrecht, one of the few mints still authorized to produce small billon denominations for local circulation. The 3-mijt valuation reflects the simultaneous use of both Flemish and Holland accounting systems during this transitional period.
