New 5 pence and 10 pence coins are being struck at the Royal Mint in the UK. These cheaper-to-produce coins contain nickel-plated steel, which unlike the older cupro-nickel coins, release up to 4 times more nickel on exposure and raise the risk of increased nickel sensitisation leading to contact dermatitis and eczema. An international study has drawn attention to this new public health risk, at a time when nickel-plated coins are banned in other countries such as Sweden.
