1 Duit Holland

The duit was the workhorse of VOC trade coinage in the Indonesian archipelago, where small-denomination copper issues dominated everyday transactions. A silver duit, however, is a different animal entirely — KM#70a represents an anomalous and short-lived experiment in silver composition for a denomination almost universally struck in copper throughout the VOC period. The Holland provincial issues were among the most heavily counterfeited in circulation, partly driving quality-control variants.

The VOC's Batavia administration frequently complained to the Heeren XVII about substandard planchets arriving from Dutch mints.
