| 背面描述 | The reverse features a naturalistic depiction of a Ringed Seal (Pusa hispida) resting on a block of ice in the foreground, rendered in fine relief against a textured field suggestive of water and ice. In the background, the head of a second Ringed Seal emerges at the water's surface, emphasising the aquatic habitat of the species. The inscription «КОЛЬЧАТАЯ НЕРПА» (Ringed Seal) arcs along the upper rim in Cyrillic lettering. |

Part of Russia's long-running "Red Book" wildlife series, which has documented endangered Soviet and post-Soviet fauna since 1993. The Ladoga ringed seal (Pusa hispida ladogensis) is endemic to Lake Ladoga — the largest freshwater lake in Europe — where its population had been severely reduced by commercial hunting and, later, industrial pollution from the Volkhov River basin. By the time this coin was issued, estimates placed the surviving population at somewhere between 3,000 and 5,000 individuals.
