Rupee - Nader Afshar Java counter-mark

In the mid-eighteenth century, the VOC faced a chronic shortage of specie on Java adequate for day-to-day trade. Rather than wait for shipments from Amsterdam or Batavia's own limited mint output, company officials counter-marked foreign silver already in circulation — in this case, rupees struck under Nader Shah's authority — to validate them for use in VOC-controlled territories. The counter-mark effectively conscripted Persian imperial coinage into Dutch colonial commerce without the expense of remelting.

The date range reflects the window during which this practice was authorized on Java, ending as improved supply chains reduced dependence on improvised monetary solutions.
