1 Crown - Elizabeth II Princess Diana, Silver Proof

Struck a decade after the 1981 wedding issue that made commemorative Diana coinage a global phenomenon, this 1991 piece was produced during a period when the Manx government had established itself as one of the most prolific issuers of royal commemorative silver in the British Isles — a reputation built largely on collector demand rather than domestic circulation. By this point, the Isle of Man's arrangement with the Crown gave it unusual latitude to issue commemoratives independently of the Royal Mint's schedule.

The marriage was publicly unraveling by 1991, though the separation would not be formally announced until the following year.
