Alderney had not issued coins under its own name before 1989. This piece marks the island's numismatic debut, authorized specifically to commemorate Queen Elizabeth II's visit and struck as a piedfort — double the normal planchet thickness — by the Royal Mint on behalf of the States of Alderney. The island, though a dependency of the Bailiwick of Guernsey, maintains a distinct administrative identity, and the decision to issue separately from Guernsey was a deliberate assertion of that distinction.
KM#P1 is exactly what it looks like in the catalog: the very first entry.
