Two rare 50p coins have sold for more £2,500 on the auction site eBay, prompting calls for Brits to check their change to see if they are in possession of a valuable coin.
The coins were issued to mark the 2012 Olympic Games, held in Britain, and were particularly rare variants.
A host of coins were developed which depicted different sports taking place in the games.
These particular 50p coins were marked with images of swimmers, but what made them special was the fact that the coins depicted lines across the swimmer’s face, representing waves.
The coin was later tweaked, so that the face was entirely visible, making this particular variant sought after by collectors.
These coins were just a couple of examples of currency that has sold for far more than the face value through auction sites of last.
For example, earlier this month a 2009 Kew Gardens 50p coin shifted for a whopping £142.
So how can you tell whether your 50p piece is actually worth more than its face value?
Read on to find out.
Don’t believe the hype
The first thing to point out is that you should be wary of both tabloid articles and asking prices online, says Luke Hearn of the Change Checker website.
Both can give a very over-inflated idea of what a coin is really worth.
"To be honest, there is a lot of misinformation written in the press regarding coins," he says.
"The first and most obvious example of this is when people list coins for a ridiculous amount on eBay when actually nobody is ever going to pay that much.
“I think the reason behind this is nothing more complicated than people chancing their arm on the off chance they may get lucky."
It's best, then, not to be too optimistic – and, if you're checking prices out on eBay, make sure you look at the prices coins have actually sold for, rather than the asking price.

What collectors are looking for
If you do find a rare coin, it'll need to be in good condition with little sign of wear and tear if you're to get any more than the face value.
Collectors are particularly keen on ‘Brilliant Uncirculated’ coins, which are made with a special superior finish.
However, it's still worth checking your change for 50p coins that were never intended for circulation but somehow have slipped out.
"This sometimes happens when some poor soul is robbed of their coin collection and the thieves simply break them out of their packaging and spend them," says Perkins.
"Some of these coins are valuable: for example, the 2011 Olympic Aquatics coin with extra lines on the swimmer's face, which was a design that was withdrawn, not adopted and shouldn't have seen the light of day.
“They are rarely offered for sale as they are rarely encountered. The withdrawn 50p in its original packaging is worth £1000-plus."
But it’s not all about the super-rare coins.
There are many far more common 50p versions that are worth a few quid to collectors.
So if you've got a spare couple of minutes, you may want to fetch your purse or wallet right now.
