A rare £2 coin that appears to be all one colour due to a design error has sold for £255 on eBay. A normal £2 consists of a yellow metal nickel-brass ring on the outside, and a grey cupro-nickel disc in the middle - but this one is all yellow.
The coin, which is dated 2009, sold for £255 exactly, plus £1.50 delivery, after attracting a flurry of 28 bids following a seven-day auction. The impressive sale prices means the £2 exchanged hands for around 127 times its face value. You can see the eBay listing here. Experts at Coin Hunter previously told reporters at The Mirror that this type of error is known as a “yellow” £2 coin. If you find one, it could be worth up to £500.
Coin Hunter says it is unclear how many of this particular error coin could be in circulation. Error coins have a fault or mistake in their design, and they're worth a mint to collectors. The reason why they’re often sought-after is because they are usually hard to come by - in some cases, they are even a complete one-off.
