Farthing
A farthing was a quarter of a penny, and ceased to be legal tender on 31 December 1960. A groat, when it was issued in England between 1351 and 1662, was worth 4 pennies; a florin was worth two shillings; two bob was two shillings. A shilling became equivalent on 15 February 1971 to 5p in the new British currency.
