1 Crown - Elizabeth II Orbiter Space Shuttle, Silver

The Space Shuttle Orbiter program had completed only four test flights before NASA declared it operational in 1982, and the Isle of Man moved quickly to issue commemorative coinage capitalizing on the early excitement around the program. The Manx Treasury was unusually aggressive in pursuing space-themed issues during the early 1980s, producing multiple crown series tied to missions and hardware before most other jurisdictions had taken notice.

KM#106a is the sterling silver variant of a base metal issue struck in the same year. The distinction matters for collectors: total mintage figures for the silver striking were considerably lower than the cupro-nickel counterpart, though precise figures are not consistently reported across major references.
