25 Dollars Standard Catalog of World Coins

Liberia's 1990s commemorative silver program was prolific to the point of embarrassment — dozens of large-format issues were contracted through private mints and marketed almost entirely to the Western collector trade, with negligible circulation or use within Liberia itself. The country was mid-civil war when many of these were struck, the Charles Taylor–led NPFL controlling much of the interior while the internationally recognized government retained nominal authority.

KM#323 falls squarely within that output. The 77-gram format corresponds to a 2.5 troy ounce planchet used across multiple Liberian issues of this period.
