 | | In the 12th century a new standard for English coinage was established by Henry II, the Sterling Silver standard of metal – 92.5% silver and 7.5% copper used in coinage. |
 | | In 1920, the silver content of all British coins was reduced from 92.5% to 50%, with a portion of the remainder consisting of manganese, which caused the coins to tarnish to a very dark color after they had been in circulation for a significant period. |
 | | The old British system of money, which evolved from mediaeval times, used a selection of coins known as guineas, pounds, Crowns, Half-Crowns, shillings, thruppence, pennies, halfpennies and farthings. |
