| 裏面の説明 | The entire reverse field is dominated by a large, precisely rendered taijitu (yin-yang) symbol, filling the coin's circular flan to the reeded rim. The design is executed with a two-tone effect: the yang (light) half is rendered in a highly polished, mirror-like proof finish, while the yin (dark) half retains a matte gilt surface, creating a striking contrast. Each half bears its corresponding small circular dot of the opposite finish, faithfully reproducing the classical Taoist duality motif. No legends or inscriptions appear on the reverse. |

Mongolia issued a substantial run of commemorative pieces in the mid-2000s under licensing arrangements that effectively outsourced design and production to European minting houses — this piece almost certainly originates from that program. The gilt copper-nickel composition was a cost-control measure that allowed the Bank of Mongolia to offer nominally gold-associated pieces at accessible price points for the collector market, with no pretense of bullion value.
KM#254a denotes the gilt variant of a base issue, the silver and standard copper-nickel versions having been struck concurrently.
