1 Crown - Elizabeth II Longest Reigning Monarch

Gibraltar has issued commemorative crowns prolifically since the 1970s, and by 2015 the territory had produced hundreds of distinct types — making individual issues from this period difficult to distinguish in the secondary market. This piece marks the moment Elizabeth II surpassed Queen Victoria's reign of 63 years, 216 days, a milestone reached on September 9, 2015.

Gold-plated copper-nickel was the workhorse fabric of the commemorative trade in this era, keeping retail prices accessible while maintaining the visual weight of a precious-metal issue.
