The term "pound" to describe a British monetary value has been in use for hundreds of years, but there was no official coin or banknote to the value of "One Pound" and called "One Pound" issued until much more recently. The modern Sovereign (with a face value of a One Pound or 20 Shillings) was reintroduced into the British currency in 1817. The first British coin with a "Pound" denomination ascribed to it was the 1820 Five Pound gold coin. The Bank of England produced One Pound notes periodically from 1797 to 1821. The first official regular issue of British One Pound note, which was actually a Treasury Note, was first issued in 1914. The first British decimal One Pound coin was issued in 1983.
