The problem occurred after all the coins from the 1p through to the £1 were redesigned last year.The designs for the 5p and 10p had been unchanged for four decades.A 'mule' is a coin that has mismatched sides - a reference to the mule being a mismatch of a horse and donkey.The change of the 20p design meant moving the year date from the tails side to the side with the Queen's head.There is an unwritten convention that designs should be changed at least every 40 years to keep the coinage fresh.The Royal Mint's usually impeccable quality control somehow slipped up and the so-called 'mule' escaped into circulation.Then it shot up to £5,000 and kept rising until the price reached £7,100.A spokesman for e Bay said: 'The winning bid was definitely £7,100, but I can't confirm yet whether the actual transaction has been completed yet.' The coins were left dateless when the 20p piece was redesigned.
This created thousands of coins without any date, a rare and valuable mistake in the world of coin collecting. However, The London Mint Office, which is a private company with no connection to the Royal Mint, is offering £50 a time to anyone who has one.The blunder occurred after a redesign of the 20p piece.The Mint does not know exactly how many undated coins were produced and released into circulation, but estimates range between 50,000 and 200,000.It is filled with genuine local women and costs just 10p per minute to call.
