25 Dollars - Elizabeth II Queen Mary I

Issued as part of a multi-coin silver series commemorating the Silver Jubilee of Elizabeth II, this piece celebrates Queen Mary I — a pointed choice given Mary's complicated reception in Protestant-majority territories. The Cayman Islands series was among dozens of Commonwealth issues flooding the collector market in 1977, many struck by the Royal Mint or contracted refiners specifically for the numismatic trade rather than any circulation purpose.

KM#16 was produced in limited proof and uncirculated formats with virtually no secondary commercial function — a straightforward bullion-adjacent collectible of its era.
