100 Dollars

The Eastern Caribbean Central Bank replaced the East Caribbean Currency Authority in 1983, and this series was among the first issued under the new institutional name — though the underlying currency and its fixed peg to the US dollar had been in place since 1965. The ECCB serves eight territories simultaneously, which creates an unusual issuing arrangement: the notes carry no country-specific designation, circulating identically across Antigua and Barbuda, Dominica, Grenada, St. Kitts and Nevis, St. Lucia, St. Vincent, Montserrat, and Anguilla.

De La Rue produced the series in London. The $100 is the highest denomination in the P#20 run, and high-value notes from small-island currency unions tend to see limited retail circulation — most movement happens at the banking level.
