Quarter farthing
The British quarter farthing ( ⁄16d) coin was a unit of currency equaling one sixteenth of a penny ( ⁄3,840 of a pound sterling). It was produced for circulation in Ceylon in various years between 1839 and 1853, with proof coins being produced in 1868. It is the smallest denomination of pound sterling coin ever minted. The coin is considered to be part of British coinage because it has no indication of what country it was minted for, being made in the same style as the contemporary half-farthing which was legal tender in Britain between 1842 and 1869.
