Liberia's commemorative silver program around 2000 was prolific to the point of controversy — the Central Bank licensed numerous foreign distributors, primarily based in the United States and Germany, to produce coins that were technically legal tender but never intended for domestic circulation. Most pieces from this period were struck by private mints in Europe and sold directly into the collector market.

KM#639 is one of dozens of issues from this licensing arrangement. Liberia itself was mid-civil war in 2000, and the "Central Bank" issuing authority was more nominal than functional during that period.
