50 Pence - Charles III Grand Prix Centenary; Gold Proof

The British Grand Prix first ran at Silverstone in 1950 as part of the inaugural Formula One World Championship season — making 2026 the centenary of the event's earlier incarnation, the 1926 RAC Grand Prix at Brooklands, which predates the FIA-sanctioned championship by over two decades. Whether the Royal Mint is commemorating the 1926 Brooklands race or stretching the centenary framing requires scrutiny; the 1950 Silverstone race is the more commonly cited founding moment of the British Grand Prix in its modern form.
