500 Tögrög Chipmunk

Mongolia has no native chipmunk species. The Siberian chipmunk (Tamias sibiricus) does range into parts of adjacent Russia and northern China, but its appearance on a Mongolian commemorative places this squarely in the modern collector-bullion market rather than any expression of national natural history — a pattern that has defined the Bank of Mongolia's silver program since the early 2000s, when the institution began licensing wildlife and novelty themes almost entirely for export to Western and Asian collector markets.
