50 Pence - Elizabeth II Commonwealth Games, Platinum Proof

The 2022 Commonwealth Games were held in Birmingham — the first time England had hosted since Manchester in 2002 — and the Royal Mint issued an unusually broad range of commemorative strikes to mark the occasion, with platinum proofs sitting at the extreme top of a tiered collector program. Platinum proof coinage from the Royal Mint in 50 pence format is genuinely rare in terms of actual mintage; the denomination is overwhelmingly struck in cupro-nickel for circulation, and precious metal proofs in this size are produced in strictly controlled, typically low four-figure or even three-figure quantities.

Spink reference H105 places this squarely in the modern decimal proof series, where platinum issues consistently command premiums well beyond their metal value on the secondary market.
