20 Dollars - Elizabeth II Nippon Maru

The Nippon Maru is a Japanese sail training vessel, the second to bear that name, launched in 1984 and operated by the Japanese government to train merchant marine cadets. The British Virgin Islands issued commemoratives of this kind under licensing arrangements common to small Caribbean territories that maintain no meaningful domestic demand for such coins — production was aimed squarely at the collector market, with the Royal Mint and private minting houses facilitating dozens of similar ship series across the 1990s and early 2000s.
