500 Tögrög Gulo Gulo Wolverine

The wolverine occupies an almost mythological place in the ecology of the Mongolian taiga and mountain steppe — a solitary scavenger capable of driving wolves from kills several times its size. Mongolia's inclusion of Gulo gulo in this wildlife series reflects genuine conservation concern: the species was already experiencing documented range contraction across Central Asia by the mid-2000s, driven by habitat pressure and trapping for fur.

Struck to .999 fineness at 31.1 grams — a standard modern bullion blank — the coin's distinction lies in its subject matter rather than its metallurgy.
