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 colour after they had been in circulation for a significant period.
The weight of this coin was instituted by Charlemagne, and the purity of 92.5% silver (i.e., sterling silver) was instituted by Henry II in 1158 with the "Tealby Penny"—a hammered coin.
All British coins produced since 1662 have been milled; the first milled coins were produced during the reign of Elizabeth I and periodically during the reigns of James I and Charles I, but there was opposition to mechanisation from the moneyers who ensured that most coins continued to be produced by hammering.
