| 表面の説明 | The obverse features a black rhodium-plated field against which the effigy of King Charles III is rendered in high relief, facing left. The portrait depicts the King in civilian dress — suit and tie — as sculpted for the Royal Canadian Mint's contemporary coinage series. The obverse legend arcs around the upper periphery, while the denomination and designer's initials SR appear in the field. The stark contrast between the matte black rhodium ground and the polished silver relief imparts a refined, modern aesthetic to the design. |

| 裏面の説明 | The reverse presents a single sugar maple leaf (Acer saccharum) engraved in meticulous detail, its characteristic five-lobed form and intricate vein structure rendered in gleaming fine silver against a black rhodium-plated field. The stark tonal contrast between the polished silver relief and the darkened ground accentuates the natural elegance of the leaf's silhouette. The country name CANADA and the date 2025 appear in the legend, accompanied by the designer's initials DK. The composition is centered on the flan, occupying the majority of the reverse field in a clean, minimalist arrangement. |

The selective black rhodium plating technique used here requires precise electroplating over specific die-struck areas — rhodium, one of the platinum group metals, is applied at a fraction of a millimeter's depth and is chemically inert enough to resist tarnish indefinitely. The RCM has refined this process over roughly a decade of bullion and collector issues, but achieving clean boundaries between plated and unplated silver at this scale remains genuinely difficult. Pieces with plating bleed at the transition zones are not unheard of in the series.
