Question: which 5 pence coins are valuable?
Answer: Old 5ps and 10ps are worth more than 5p or 10p – like copper coins before them, the value of the metal in 10p and 5p coins increased until they were being made at a loss. In 2012 the Royal Mint started making 5ps and 10ps out of nickel-plated steel, instead of a copper-nickel mix (75% copper, 25% nickel).
