How To Make 20p Into £50.00!

just look in your pocket! in an embarrassing mistake the Royal Mint put hundreds of undated 20 pence pieces into circulation, There is an unwritten convention that designs should be changed at least every 40 years to keep the coinage fresh, the change of the 20p design meant moving the year date from the tails side to the side with the Queen's head, however, thousands of coins were minted using the old version of the Queen's head, which does not have the year date, and the new version of the tails side, which also does not have a date, this created thousands of coins without any date, a rare and valuable mistake in the world of coin collecting, out of interest this coin is called a 'mule' the Royal Mint's usually impeccable quality control somehow slipped up and the so-called 'mule' escaped into circulation, a 'mule' is a coin that has mismatched sides - a reference to the mule being a mismatch of a horse and donkey, no one knows how much the undated 20p is worth, 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.
