1 Crown - Elizabeth II Platinum Wedding - Platinum Decade, Platinum Plated

Issued to mark the 70th wedding anniversary of Elizabeth II and Prince Philip — the first British royal couple to reach a platinum anniversary — Gibraltar has long exploited its Crown dependency status to produce commemorative coinage that the Royal Mint itself would never sanction. This piece is the copper-nickel variant with platinum plating, a budget issue sitting alongside a genuinely platinum-struck version in the same series. KM#1608a distinguishes it from its precious-metal counterpart.
