Mongolia's 1937 coinage was produced under heavy Soviet influence, with the Mongolian People's Republic functioning as a satellite state of the USSR throughout this period. The physical specifications of this issue — notably heavy for a minor denomination — reflect Soviet-era design philosophy favoring durability over economy of materials. Aluminium bronze was the standard alloy across Soviet-aligned states at the time, chosen for its resistance to corrosion in extreme continental climates like Mongolia's.
