| 正面描述 | The obverse depicts the effigy of Queen Elizabeth II, accompanied by the Public Seal of Niue within the field. The national legend 'NIUE' appears alongside the royal portrait, with the denomination '250 DOLLARS' and date '2021' inscribed in the legend. The inscription '1 TROY OZ .9999 GOLD' attests to the coin's bullion specification. The design incorporates the motto 'ATUA NIUE TUKULAGI' as part of the national seal imagery. |

| 背面描述 | The reverse presents a highly detailed portrait of Leonardo da Vinci in three-quarter view, depicted as an elderly bearded man wearing a beret, his right hand raised in a contemplative gesture holding a stylus or brush. Surrounding the central portrait, rendered in fine relief against the field, are several of da Vinci's renowned technical drawings and inventions, including flying machines, an ornithopter with bat-like wings, a mechanical aerial screw, and technical manuscript pages with mirror script. A bird in flight appears in the upper right field, reinforcing the aeronautical theme. The cursive facsimile signature 'L. da Vinci' is inscribed in the lower right field, with engraver's initials visible at the rim. |
