10 Dollars - Elizabeth II Vienna

Part of the "Famous Cities" bullion miniature series struck by the Austrian Mint on behalf of Pacific island issuers, this piece belongs to a category of fractional gold issues that exist primarily as collectibles rather than instruments of genuine circulation. The Solomon Islands has issued dozens of these licensed pieces with no meaningful domestic monetary function.

The Austrian Mint's .9999 fine gold standard — four nines purity — became their benchmark following the introduction of the Vienna Philharmonic in 1989.
