Designed by Canadian artist Pandora Young, the 2025 Proof Dollar’s reverse presents a circular interpretation of the Tomb of the Unknown Soldier at the National War Memorial in Ottawa, Ontario. The three rings allude to the sarcophagus’s three-tiered construction in dark Caledonia granite, as depicted in the centre of the design, while the Tomb’s four base corner pieces—three replicas of the Memorial (Silver) Cross, each bearing the Royal Cypher of a different ruling monarch (George V, George VI, Elizabeth II) since the award’s inception in 1919, plus a replica of a poppy—are artfully positioned around the edge, ultimately forming a more circular interpretation to help frame the top-down view. The Tomb’s bronze overlay is also re-created, with branches of maple and laurel leaves wrapped around a medieval sword and First World War-era helmet; these are surrounded by roses and poppies (in the 11 o’clock position) that have been laid in commemoration of those who selflessly gave their all while serving their country. The obverse features the effigy of His Majesty King Charles III by Canadian artist Steven Rosati.
