This piece belongs to Liberia's sprawling "Cities of the World" gold program from the early 2000s, a series the Central Bank issued primarily for the international collector market rather than domestic circulation. Liberia had essentially no functioning economy at the time — the second civil war erupted in 1999 and would grind on until 2003 — making collector bullion exports one of the few reliable sources of hard currency the state could generate.
