During the Great Recoinage of 1816, the mint was instructed to coin one troy pound (weighing 5760 grains) of standard (0.925 fine) silver into 66 shillings, or its equivalent in other denominations. This effectively set the weight of the shilling, and its subsequent decimal replacement 5 new pence coin, at 87.2727 grains or 5.655 grams from 1816 to 1990, when a new smaller 5p coin was introduced.
