This rare 1p coin was sold for £72,000 at auction

You might have a fortune in your piggy bank! A rare old penny was last week sold for a whopping £72,000. The 1933 Lavrillier Pattern Penny broke a world record for any copper or bronze coin sold at auction when the hammer went down at AH Baldwin and Sons in London. Why so valuable? Well, 1933 pennies are apparently extremely rare anyway. The Royal Mint produced a surplus of 1p coins in 1932, meaning no more currency versions were produced the following year. Only seven pennies were made bearing the 1933 date - and they were for 'ceremonial and record purposes'. This particular coin is even more rare - one of only four ever made - meaning the item garnered bids from all over the world. The fight finally came down to just two telephone bidders, who battled it out for over five minutes before the hammer came down.
You're unlikely to find a version of this particular coin in your money box, as the other three are already accounted for. One penny is being stored in the Royal Mint Museum, while the others have private owners. Still, it's worth checking your coins every now and then in case you've got a potential fortune in your pocket without even realising it.
