Gibraltar's Crown series has long served as a vehicle for commemorative issues tied to British royal events, and the 2017 Platinum Wedding anniversary — marking 70 years of marriage between Elizabeth II and Prince Philip — generated an unusually large family of variants. This platinum-plated copper-nickel piece is the base-metal entry in that hierarchy, sitting below both the solid silver and the genuine platinum strikes issued concurrently. The KM#1602a designation reflects its plated status as a distinct catalogued type rather than a simple variety.
