10 Dollars Battle of Britain

Liberia's 1990s commemorative program was essentially a foreign-currency operation — these coins were designed, marketed, and distributed almost entirely to Western collectors, with no meaningful circulation in Liberia itself. The Pobjoy Mint in Surrey struck the majority of them under contract. Whether KM#305 falls into that production run or one of several competing contractors working Liberian licensing at the time is worth verifying against the specific edge and die characteristics.

The Battle of Britain, fought between July and October 1940, marked the first major campaign decided entirely by air power, and the RAF's victory foreclosed a German invasion that Hitler had already conditionally authorized under Operation Sea Lion.
