Buckingham Palace has appeared on Royal Mint commemoratives before, but the piedfort format here reflects a deliberate positioning decision rather than a minting tradition — British pieforts were effectively revived as a collector product category in 1982 after a centuries-long gap, and they have since become a reliable premium tier in the Mint's annual program. At double the standard coin thickness, the specification demands a slower, higher-pressure strike cycle to fill the dies properly.
