The tögrög was introduced on December 9, 1925 at a value equal to one Soviet ruble, where one ruble or tögrög was equal to 18 grams (0.58 ozt) of silver. It replaced the Mongolian dollar and other currencies and became the sole legal currency on April 1, 1928.

Möngö coins are not in circulation as currency any longer, as they are of negligible value. They are sold to tourists and as novelties and collectibles now.
