A COIN expert has revealed how to look for a rare 50p error coin that could be worth £100s.

The Benjamin Button coin is a popular commemorative fifty pence for coin collectors, though it often isn’t worth much.

However, there are several knocking about that could be worth up to £70.

TikToker @thecoincollectoruk posted a video encouraging viewers to look for this special coin.

To find it, you’ll need to look at the way Benjamin Button is positioned in comparison to the late Queen.

That’s because some of the coins contain a rare rotation error which shows Benjamin’s head titled further left.

Instead of being parallel and level with the Queen’s head, it is positioned more towards the left.

So keep an eye out for this coin as you may be able to get big cash for it.

At the time of writing, we saw one that had sold for £70 on eBay recently, while another went for £50.

But sellers could get lucky as one sold for £255 back in 2021 so you may be able to get a bit more.

So get looking through drawers, down sofas and in wallets.

How do I check if my coin is rare?

Rare coins and valuable notes can be worth tens of thousands of times their face value.

But sometimes it’s just tiny differences which make them so lucrative.

The most valuable coins tend to be ones with low mintage numbers or an error.

Those qualities typically make them valuable to collectors.

Your next step would be to check if your coin is still available to purchase in superior Brilliant Uncirculated quality from an official Royal Mint distributor, according to Change Checker.

Certified Brilliant Uncirculated coins have been specially struck to a superior unblemished quality which set them apart from the coins you may find in pockets.

Selling a coin at auction or through a dealer

There are many different factors to consider when trying to value a coin, including its condition and mintage, so it’s important to do your homework first.

If you’ve got a coin that you would like to sell at auction, you can contact The Royal Mint’s Collectors Service.

It has a team of experts who can help you to authenticate and value your coin.

You’ll need to enquire via email, and a member of the valuation team will contact get back to you.

Take a picture of your coin and attach this to the email – you can find the details on The Royal Mint’s website.

Be aware that you will be charged for this service though – the cost will vary depending on the size of your collection.

If you are looking to buy a coin online through a marketplace such as eBay, it’s important to know exactly what you are purchasing.

This is because anyone can list a coin on eBay and charge whatever amount they wish.

You should also be wary of fakes online – and keep in mind that on eBay a buyer could pull out, which means the coin won’t have sold for the price it says it has.
