etc., and I believe the evil is daily increasing, as the spurious money is carried into circulation by the lowest class of manufacturers, who pay with it the principal part of the wages of the poor people they employ". Boulton's contract in 1797 to produce the Cartwheel pennies and twopences, thwarting the counterfeiters, did not extend to producing the halfpenny, though Boulton had expected that it would, and had prepared patterns of the appropriate size and weight in accordance with his ideas on the intrinsic value of copper coins. The reason the government gave for the omission of the denomination from the contract was that the large number of de facto halfpennies (including tokens and fakes) would be driven out of circulation and Boulton would be unable to produce enough coins to meet the demand that would ensue. Public demand for legal halfpennies soon forced the government to change its mind, and in 1798 a contract was issued to Boulton for him to produce halfpennies and farthings dated 1799. However, in the meantime the price of copper had risen, and consequently the weight of the coins was reduced slightly, which resulted in them not being as popular as expected. In 1806 a further 427.5 tons of copper was struck into halfpennies by Boulton, but the price of copper had risen again and the weight was even less than the 1799 issue. This time, however, there was no unfavourable reaction from the public, so perhaps the national obsession with "intrinsic value" was over. Great Britain and beyond, 1800–1970 George III halfpennies were produced in three distinct phases: 1770–1775 (all years). Weight 9.2–10.8 grams, diameter 29–30 millimetres.
