100 Dollars

The Eastern Caribbean Central Bank, established in 1983 as successor to the Eastern Caribbean Currency Authority, issues a shared currency across eight territories — Antigua and Barbuda, Dominica, Grenada, Montserrat, St Kitts and Nevis, St Lucia, St Vincent and the Grenadines, and Anguilla. The logistical challenge of maintaining a single note across politically distinct jurisdictions, some with populations under ten thousand, is genuine. Thomas De La Rue has printed the series throughout, providing a consistency the member states could not individually sustain.

The P#51 series introduced updated security features in the early 2000s, though the note's thread and watermark specifications remain modest by the standards De La Rue was producing for other clients at the same time.
