How much is the 2012 London Olympics 50p coin worth and how can you tell if you’ve got one?
If you have a very rare version of the swimmer coin, you might be able to make thousands from it
CAST your mind back to 2012 and surely the first thing that pops into your head is the London Olympics.
The whole country was so excited about the sporting event, which is why the Royal Mint brought out some commemorative coins to mark it.
If you've been keeping up with the news, you'll know there's big cash to be made from rare money.
The AK47 plastic fivers have been exchanging hands for thousands on eBay, and you could make over £30 if you have one of these commemorative 50p pieces.
So how much could you be sitting on if you have some of the London 2012 50ps?
The Royal Mint came up with 29 different designs for the range, but it all depends on which one you have.
That's because there were a lot more versions of some produced than others, so the rarer the coin the more it'll be worth.
If you managed to get a full set of the coins, you might be able to exchange them for £35 at auction.
It's perhaps less exciting news if you've got a coin emblazoned with the football, wheelchair rugby, wrestling character though, as those will only net you between £3 and £4.
Other versions were in honour of badminton, archery, boxing, fencing and handball. There's a full list on the .
The biggest hitter is the version which has water passing directly over the swimmer’s face on it.
There were only 600 coins created before the design changed slightly to show a swimmer’s face but if you have one it could earn you up to £3,000 if you sell it on eBay.
There are many other coins which could bring you a bundle too, here we list eight which are worth a fair whack.
