All of Liberia's coinage has been struck in the United States, as it has never had its own mint.
For most of the period from 1989 through to 2003, Liberia was in a state of civil war, with various rival factions claiming to be the "real government of Liberia" and the internationally recognized government not actually controlling much of the territory within the country.
Private mints love it when countries fall into anarchy like this; it means that they can churn out "coins" in that country's name, without needing to bother getting permission from that country's government to make the coins, because with the war happening nobody has any way of checking whether the "coins" are in fact legal tender coins from that country. Many coins in the name of Liberia are in fact just "unofficial coins", medals issued by private mints in America, with nobody in either the internationally recognized Liberian government nor the rebel factions aware of those coin's existence.
This is also the reason why most of these "coins" from this time period celebrate people and events that don't really have anything to do with Liberia; they're all made and produced in America for sale to American buyers, with designs aimed to appeal to Americans, with none of the coins ever actually entering Liberia at any time.
Somalia is another anarchistic country that private mints use as their flag of convenience for churning out such coins.
Looking your coin up on the NGC world coin database, I find
this entry; the "X" number at the top of the page indicates it is now considered an "unofficial" coin, with no legal tender status. Which does not surprise me, as most of the coins actually authorized by the Liberian government bear the country's coat of arms on the obverse.
