5 Pounds - Elizabeth II Long to Reign Over Us - Longest Reigning Monarch

Issued in 2016 to mark Elizabeth II surpassing Victoria as Britain's longest-reigning monarch — a milestone that had actually occurred in September 2015, when she reached 63 years and 216 days on the throne. Gibraltar, as a British Overseas Territory, has a long history of issuing commemorative crown-sized pieces tied to royal events, often producing multiple variants simultaneously for the collector market. The selective gold plating on this issue is a production choice driven squarely by retail appeal rather than numismatic tradition.
