You might think a £2 coin is worth just that: two pounds.

But there are some rare variants on the coin, and limited edition version, that are worth a lot more to collectors, and could fetch you a pretty penny at auction.

Here are the most valuable £2 coins in the UK right now, and how much they are worth.

Charles Dickens 50p

In August of this year, an eBay user sold two rare £2 coins for £3500, with a Charles Dickens £2 coin being one of these two coins.

Another of these special Charles Dickens coins is also up for sale on the auction website, being advertised with a £1000 price tag due to its minting errors.

The seller, known as jubar_3434, claims in its listing that these minting errors makes the coin “very rare”.

The listing explains that the dots around Queen Elizabeth’s head disappear halfway around and that the milled wording around the coin is upside down.

These two minting errors are the same as advertised on the coin which sold in August, and add to the coin’s value.

‘Inverted Effigy’ £2

These £2 coins are the result of the slipping of a piece of the Royal Mint’s machinery during the striking process.

It is not confirmed how many may be out there, though estimates point to figures around the 3,000 mark, making them very rare indeed.

If the Queen’s head on your coin is rotated by around 150 degrees in relation to the back side (which features an image of Britannia), you could be in possession of a coin with a collector’s value of around £75.

NI Commonwealth Games £2

Just under a million of these £2 coins celebrating Northern Ireland’s participation in the Commonwealth Games of 2002 were minted, making them the rarest variant of the £2 coin around.

Part of a set depicting the four home nations – Wales, England and Scotland versions of the same coin are also highly sought after – if you have one in your possession, an asking price of £30 is not unreasonable to collectors.

2015 Britannia £2

These £2 coins won’t make you rich; collectors seem to only be paying just over their intended value.

But £2 coins minted in 2015 are relatively rare in the grand scheme of things, so you can expect one of yours to sell for at least double its legal value, should you intend to part ways with it.

Properly aligned (unlike the ‘Inverted Effigy’ coin featured above), 2015 £2 coins with the image of Britannia on them can be worth around £6 to collectors.
