500 Tögrög Year of the Dog, gilt

Mongolia's lunar series pieces from this period were struck at the Kremlin's Monetny Dvor in Moscow under contract — a common arrangement for smaller nations issuing collector silver at the time. The Year of the Dog falls in the twelve-year Mongolian lunar cycle drawn from the same Chinese calendrical system adopted across Inner Asia, where 2006 corresponded to the Wood Dog year specifically.

The gilt designation indicates selective gold plating applied at striking, not post-mint enhancement — a distinction that matters for attribution against the non-gilt KM#251.
