25 Markkaa Lahti

Issued to mark the 1978 Nordic Ski Championships held in Lahti — a city that has hosted the event more times than any other — this coin was part of Finland's growing commemorative program of the 1970s, which leaned heavily on silver-clad issues at .500 fineness to keep production costs manageable while maintaining a premium feel. Lahti's Salpausselkä ridge has been a fixture of competitive Nordic skiing since the 1920s.
