50 Pence - Charles III Grand Prix Centenary; Silver Piedfort

The British Grand Prix has been held at Silverstone since 1950 — the very first round of the inaugural Formula One World Championship. The circuit itself was a repurposed RAF bomber base, its perimeter tracks hastily converted for motorsport in the years immediately after the war.

Piedfort strikes double the standard flan thickness, a format revived by the Royal Mint in 1982 after centuries of dormancy. The 2026 date puts this issue ahead of the centenary itself, a common Royal Mint practice for commemorative pieforts sold as collector sets.
