19th century

By 1802, the production of privately issued provincial tokens had ceased.^[6][7] However, in the next ten years the intrinsic value of copper rose. The return of privately minted token coinage was evident by 1811 and endemic by 1812, as more and more of the government-issued copper coinage was melted down.^[7] The Royal Mint undertook a massive recoinage programme in 1816, with large quantities of gold and silver coin being minted. To thwart the further issuance of private token coinage, in 1817 an Act of Parliament was passed which forbade the manufacture of private token coinage under very severe penalties.^[7] Copper coins continued to be minted after 1797, through the reigns of George III, George IV and William IV, and the early reign of Queen Victoria. These later coins were smaller than the cartwheel pennies of 1797, and contained a smaller amount of copper.^[5]

In 1857 a survey by the Royal Mint found that around one third of all copper coinage was worn or mutilated, often by advertisements. Two years later Thomas Graham, the Master of the Mint, convinced William Ewart Gladstone, then Chancellor of the Exchequer, that so large a part of the copper coinage must be taken out of circulation that it was worth introducing a whole new coinage which would be "much more convenient and agreeable in use". These new coins were minted in bronze, and their specifications were no longer constrained by the onerous requirement that their face value should match the value of the base metal used to make the coin. They were introduced in 1860 and a year later the withdrawal of the old copper coinage began.^[8]

20th century

The specifications of the bronze version of the penny were a mass of 9.45 g (0.333 oz) and a diameter of 30.86 mm (1.215 in),^[9] and remained as such for over a hundred years. Pennies were minted every year of Queen Victoria's reign, and every year of Edward VII's reign. George V pennies were produced every year to the same standard until 1922, but after a three-year gap in production the alloy composition was changed to 95.5% copper, 3% tin, and 1.5% zinc, although the weight and size remained unchanged (which was necessary because of the existence by then of large numbers of coin-operated amusement machines and public telephones). Thereafter, pennies were minted every year for the remainder of George V's reign, although only six or seven 1933 coins were minted, specifically for the king to lay under the foundation stones of new buildings; one of these coins was stolen when a church in Leeds was demolished in the 1960s, and its whereabouts is unknown.^[10]

A few pennies of Edward VIII exist, dated 1937, but technically they are pattern coins i.e. coins produced for official approval, which it would probably have been due to receive about the time that the King abdicated.^[11]

Pennies were not minted every year of George VI's reign: None was minted in 1941, 1942 and 1943. Pennies minted in 1950 and 1951 were for overseas use only. One 1952 penny, believed to be unique, was struck by the Royal Mint.

The worldwide shortage of tin during the Second World War caused a change in the alloy in 1944 to 97% copper, 0.5% tin, 2.5% zinc, but this bronze tarnishes unattractively, and the original 95.5% copper, 3% tin, 1.5% zinc alloy was restored in 1945.

Because of the large number of pennies in circulation there was no need to produce any more in the 1950s, however a large number of specimen sets were issued in 1953 for Elizabeth II's Coronation. At least one 1954 penny was struck, apparently for private internal purposes at the Royal Mint, but it was not until 1961 that there was a need for more pennies to be minted, and production continued each year until 1967, and afterwards (as pennies continued to be minted with the date 1967 until 1970). The 97% copper, 0.5% tin, 2.5% zinc alloy was used again for the 1960s pennies. Finally, there was an issue of proof quality coins dated 1970 produced to bid farewell to the denomination.
