Although the Olympic Games in London took place in 2012, you might still have some souvenirs or memorabilia from the event and it could make you a few quid.

Leading up to the Olympics, you might have noticed some new coins in your change and if you kept them, you could be in luck as one of the 50p coins has sold for 32x its face value on eBay.

While some of the 50p coins that were released feature designs of athletes participating in different sports, one explained the offside rule in football.

It was the 2011 50p coin that features the offside explanation that sold for £16 in Warrington.

The coin, described as "unique" by the seller, shows part of a football pitch and an example of when someone would be considered offside and not offside.

The 2012 Olympic Games logo can also be seen at the top of the 50p coin which sparked a mini bidding war on the online auction site.

Olympic Games coins considered some of the rarest 50p's in circulation in the UK

Some of the Royal Mint’s rarest 50p coins are from the 2012 Olympic Games collection.

The wrestling, football and judo coins are among the most valuable and only 1.1 million of each of these coins were produced.

The rarest 50p coin is the Kew Gardens design which was released to mark the 250th anniversary of the gardens in 2009. Only 210,000 coins were ever minted with this design.
