Beginning in 1860 and continuing for several years, Britain replaced its copper coinage with bronze pieces. The copper coins (principally the penny, halfpenny and farthing) had been struck since 1797 in various sizes, all of which were seen as too large. Over time, the copper metal wore or oxidised, or had advertising punched into it, and there were also counterfeits and foreign coins in circulation. The state of the copper coinage was ascertained by a survey in 1856 and 1857 in connection with the Royal Commission on Decimal Coinage. Though the commission recommended no action on moving toward decimalisation, the Master of the Mint, Thomas Graham, persuaded the Chancellor of the Exchequer, William Gladstone, that it would be an opportune time to replace the copper coinage with smaller, lighter coins of bronze, which would be more durable. Gladstone secured authorising legislation and a vote of funds in parliament. The Chief Engraver of the Royal Mint, Leonard Charles Wyon, was tasked with rendering designs for the new coinage. Wyon produced an obverse for the new coins depicting Queen Victoria, who modelled for him multiple times and let her views be known, leading to delays as Wyon sought to secure her approval. The reverse featured Britannia, as Wyon had been directed. There was initially some controversy over the Latin abbreviations in the inscriptions on the new issue, with some believing that there were errors that might require it to be withdrawn. With the aid of two outside firms, the Royal Mint struck sufficient of the new bronze coins that it started calling in the copper pieces in 1861, a process complete after 1877, though less than half, in terms of value, of the extant coppers were paid in. The new coins remained current until the run-up to decimalisation in 1971, except for the farthing, which was demonetised from 1 January 1961.

The A4053 Coventry ring road is a 2.25-mile (3.62 km) ring road in Coventry, England, which forms a complete dual-carriageway loop around the city centre. The road encompasses the old and new Coventry Cathedrals, the city's shopping areas and much of Coventry University. With the exception of one roundabout at junction 1, the ring road's nine junctions are entirely grade separated and closely spaced, with weaving sections between them, some as short as 300 yards (270 m), giving the road a reputation for being difficult to navigate. The junctions include connections with three other A roads: the A4114, A4600 and A429. From the 1930s, Coventry City Council began replacing the city's narrow medieval streets with modern roads, to cope with a rapidly growing population. City architect Donald Gibson began work in 1939 on a city centre redevelopment plan which expanded in scope following World War II, in which large areas of the city were destroyed by German bombs. The shopping area was rebuilt first, followed by the ring road, which was constructed in six stages from 1959. Early stages were built with at-grade junctions, cycle tracks and footpaths, envisaged as a surface-level linear park. Following traffic surveys in the early 1960s, however, the council amended the design to include grade separation and the weaving sections. Research by the city engineer indicated that it was the first urban road in the world to use this configuration at such a small scale. The road was completed in 1974, with an overall cost of £14.5 million (equivalent to £190,900,000 in 2023).
