From 1947 to 2012, all "silver" coinage in the UK was made from cupronickel, but from 2012 onwards the two smallest cupronickel denominations were replaced with lower-cost nickel-plated steel coins. In 1968, Switzerland adopted the far cheaper 75:25 copper to nickel ratio then being used in Belgium, the United States and Germany. In Europe, Switzerland pioneered the nickel billon coinage in 1850, with the addition of silver. The successful use of cupronickel in coinage is due to its corrosion resistance, electrical conductivity, durability, malleability, low allergy risk, ease of stamping, antimicrobial properties and recyclability.
