The coin, in detail
About this coin.
The one-ounce Platinum Britannia brings Philip Nathan’s standing figure to the Royal Mint’s platinum bullion collection. The 2026 coin has a £100 denomination, a 32.69 mm diameter and Martin Jennings’ portrait of King Charles III on the obverse.
A latent padlock-and-trident image, micro-text, patterned waves and shield lines are built into the reverse. Together they add fine visual detail and help distinguish the coin. The photograph shows the 2026 edition; confirm the available year and packaging with GoldRock.
