How 4 lines & series of dots on your 50p could mean it’s worth 15 TIMES it’s value – check your change now

FOUR lines and a series of dots on a 50p coin could mean its actually worth 15 times its value.

If you find a peculiar-looking coin amongst your change then you could be in for a treat.

More than one million 50p coins with a number of dots, four stripes and two wrestlers engraved on the front are circulating around the UK.

The coins were struck to celebrate the London 2012 Olympic Games and are worth £7.50 – a whopping 15 times their usual value.

Uncirculated versions of these coins are worth even more and can sell for £12.

It comes as The Royal Mint, the UK’s official maker of British coins, put 29 coins into circulation in 2011 to mark the 2012 London Olympics.

And because only a limited amount were minted, some have been known to sell for whopping amounts.

More than a decade after they were first struck, some are still out there – and could be worth up to £150.

What is the rarest Olympic 50p coin?

In most cases, a coin is valuable if a low amount were put into circulation – known as its mintage figure.

Generally, the lower a coin’s mintage figure, the more you will be able to sell it for in an auction, on eBay or Facebook Marketplace.

But this isn’t always the case and some coins have been known to sell for more than others despite more having been put into circulation.

You can find out what a coin’s mintage figure is by going on The Royal Mint’s website.

Meanwhile, some coins are also considered rare when there was a mistake in the manufacturing process.

These are commonly known as “error” coins, and there are usually just a few in circulation.

When it comes to the 50p pieces, the football 50p coin is the rarest out of the Olympic set, according to The Royal Mint.

Just 1,125,500 of the coins, showing the popular sport, were minted.

However, the football 50p is not as rare as the Kew Gardens 50p piece, of which there are only 200,000 out there.

The Kew Gardens piece was minted a few years earlier than the Olympic collection and has been known to sell for up to a whopping £895 on eBay in the past.

The coin to fetch the most in the Olympic range in recent months is the Aquatics error coin though, which sold for £150.

The error in the design makes it more valuable to collectors, just like several other rare error coins out there too.

Otherwise, the 2012 aquatics coin with the updated design is one of the more highly circulated coins with 2,197,000 released.
