Depicts Imatra hydropower plant, country name in Finnish above and Swedish below, engraver's initial (N) in the centre.

The Imatra hydropower plant, completed in 1929, is located in the centre of the city of Imatra. The hydropower plant is Finland’s biggest. Its output is 192 MW and its head is 24 meters. One Kaplan and six Francis turbines. Average annual production covers the annual electricity use of 50,000+ households with electric heat.

Imatra rapids are Finland’s oldest tourist attraction, and people have come even from abroad to admire their surging white waters as early as the 18th century.

Depicts the historic coat of arms of Karelia, a region of Finland surrounded by the value and the date above. Engraver's initial (T) and the mint's logo (lion) on the right.

Karelia is a historical province of Finland that Finland partly ceded to the Soviet Union after the Winter War of 1939–40. The Finnish Karelians include the present-day inhabitants of North and South Karelia and the still-surviving evacuees from the ceded territories.

The coat of arms of Karelia in Finland were first used in 1562, although the arms were probably presented at the burial of Gustav Vasa in 1560. The blazon for the arms may be translated as follows: A golden crown above two duelling arms, the right guantleted arm holding a sword and the left mailed arm a scimitar, all silver except for golden hafts and gauntlet joint. Ducal coronet. The two hands holding a sword and a scimitar are generally seen as symbol of Karelia's position between the Swedish and Russian realms.
