| 背面描述 | The reverse depicts the Explorer 1 satellite — America's first successful Earth-orbiting satellite launched in 1958 — shown in dynamic diagonal flight against a star-studded space field, with bold radiating lines suggesting speed and transmission signals. A partial globe in the upper right field indicates the satellite's orbital trajectory around the Earth. The denomination 50 FIFTY DOLLARS is inscribed in the right field. The legend FIRST AMERICAN SATELLITE - 1958 arcs along the upper border. The mintmark M for the Medallic Art Company appears in the lower exergue. |
