10 Dollars

The Board of Commissioners of Currency was Singapore's sole note-issuing authority from 1967 until the Monetary Authority of Singapore absorbed that function in 2002. This orchid series, introduced in the early 1970s, was the second full definitive issue for the independent republic and marked a deliberate shift away from the transitional Singaporean dollar notes that had carried over design DNA from the Board of Commissioners of Currency, Malaya and British Borneo.

Thomas De La Rue printed the series throughout its run, a relationship that predated independence. The P#11a designation covers a date range suggesting the plates saw sustained use across at least four print years, which occasionally produces minor shade variations between early and late printings.
