OBVERSE

The obverse of this coin features the fourth effigy of Queen Elizabeth II, a portrait imbued with dignity, continuity, and royal presence. Calm. Formal. Timeless. The design recalls an era of British numismatics immediately recognized by collectors, where every line of the portrait carried the authority of the Crown and the memory of an unparalleled reign. Polished in luminous Proof, the platinum surface lends the effigy a crisp, ceremonial gleam. This edition marks a world first: the iconic effigy appears on an official platinum coin from the Royal Mint, elevating a historic portrait into a new form of precious metal. 

REVERSE

The reverse bears the issuing authority of the United Kingdom, along with inscriptions related to the coin's legal tender status: "2026" – the year of issue, and "100 POUNDS" – the face value.
