2500 Tögrög Year of the Horse

Mongolia's 2002 lunar issues were part of a broader wave of high-weight silver commemoratives produced for the East Asian collector market during the early 2000s, when demand for 5-ounce and kilo-format coins was expanding rapidly among dealers in Hong Kong and mainland China. The Bank of Mongolia, like several Central Asian sovereigns in this period, contracted production to established foreign mints rather than striking domestically.

The 155.515g specification is exactly 5 troy ounces — a round figure that drove the commercial logic of the issue as much as any numismatic consideration.
