250 Tögrög Soyuz 39 - Saljut 6

Soyuz 39 launched in March 1981, carrying Soviet cosmonaut Vladimir Dzhanibekov and Mongolian pilot Jugderdemidiin Gürragchaa — the first Mongolian in space — to the Salyut 6 station under the Intercosmos program, which allowed Warsaw Pact and allied nations to fly crew members on Soviet missions. Gürragchaa, a military pilot with no prior spaceflight experience, spent just under eight days aboard before returning to Earth.

Mongolia issued a string of commemorative silver pieces through the 1990s tied to space milestones with no domestic connection beyond national pride in Gürragchaa's flight.
