Mongolia's 1955 series was the country's first major postwar note redesign, produced entirely within the Soviet printing establishment at Goznak in Moscow — a detail that reflects how thoroughly Mongolian monetary infrastructure was integrated into the Soviet system during this period. The involvement of named Mongolian designers, Shi-bu and D.Amgalan, is unusual for the era; most satellite-state issues of the 1950s carry no local design credit whatsoever.

The series was succeeded in 1966, limiting the active circulation window to roughly a decade.
