15 Möngö

The 1959 Mongolian möngö series was issued under the Mongolian People's Republic during a period of near-total Soviet economic integration — the tögrög itself was pegged to the Soviet ruble, and coin designs were approved in close coordination with Moscow. Aluminium coinage at this weight was a deliberate Soviet-bloc choice, reflecting both postwar metal allocation priorities and the practical reality of a nomadic pastoral economy where coin loss was high and production costs needed to stay minimal.
