| 正面描述 | The official Seal of the Republic of the Marshall Islands is rendered in high relief at the centre of the obverse, depicting a frigate bird above ocean waves with a traditional Marshallese sailing canoe to the right and palm trees to the left, flanked by two crossed traditional sticks and surmounted by a radiant sun. A chain-link border frames the entire design. The upper legend reads REPUBLIC OF THE MARSHALL ISLANDS, the lower legend reads JEPILPILIN KE EJUKAAN, with the denomination $50 to the left and the date 1994 to the right. The word SEAL appears on a ribbon banner at the base of the central device. |

The Marshall Islands began issuing commemorative coinage in the late 1980s under a licensing arrangement that outsourced production entirely to foreign mints, making these coins legal tender in name while functioning almost exclusively as collector pieces. The Neptune issue belongs to a space-themed series tied loosely to NASA's Voyager 2 mission, which had completed its Neptune flyby in August 1989 — the first and, to date, only spacecraft to observe the planet at close range.
Voyager 2's Neptune encounter confirmed the existence of the Great Dark Spot and detected winds exceeding 2,100 kilometers per hour, the fastest recorded in the solar system at the time.
