1 Rupee

Struck under British military administration following Thomas Stamford Raffles's appointment as Lieutenant-Governor of Java in 1811, these rupees were produced to meet an acute shortage of acceptable coinage on the island. The Dutch colonial monetary system Raffles inherited was in disarray, and locally minted silver was a practical necessity rather than a political statement.

The .792 fineness places it slightly below the standard of contemporary British Indian rupees, a deliberate economy given the uncertain tenure of British control — which ended exactly as expected when Java was returned to the Dutch under the Anglo-Dutch Treaty of 1814, with the handover completed in 1816.
