1 Dollar - Elizabeth II Brexit

Issued in anticipation of the June 2016 Brexit referendum, this Cook Islands piece belongs to a wave of privately commissioned commemoratives produced by the European Mint and similar operations that flooded the market before the vote. Cook Islands has long served as a licensing authority for such issues — its monetary agreement with New Zealand permits legal-tender coinage while placing no meaningful restriction on what themes outside mints can attach to it. The result is a sprawling catalog of topical pieces with negligible circulation history and collector value driven almost entirely by silver spot.
