Rare 20p coin sells for £60 on eBay - and there could be thousands in circulation

A rare 20p coin which is missing the date has sold for almost £60 on eBay.

This rare coin is called an "undated" or "mule" 20p and there might be thousands like it in circulation. The error occured when the Royal Mint changed the coin's design in 2008, moving the date from the back of the coin to the front, reports The Mirror Online.

However, sometimes the old way was used by mistake, so some coins don't have a date on either side. According to Change Checker, the Royal Mint thinks there could be up to 250,000 of these coins out there.

According to the coin experts, this could be the first time in over 300 years that a coin has been given out without a date.

One of these special 20p coins was just sold on eBay for £59. 98 on February 27. The auction started at 99p and after seven days, 13 people had placed a bid. The person who won has to pay £8 more to get it delivered.

The eBay listing said: "Selling up my collection of coins so many others to be listed don't miss out. Dateless 20p coin. All coins will be sent as special delivery by Royal Mail."

Coins with mistakes on them can be worth a lot of money to collectors because they might be the only one or one of just a few, but a coin is only worth as much as someone will pay for it.

If you're thinking about buying a coin, watch out for fake ones being sold on eBay so you don't lose your money. You can ask the Royal Mint to check if a coin is real.

The Royal Mint makes between three million and four million coins every day, so it's hard for them to know exactly how many mistake coins there might be. But they do sometimes make mistakes - so keep an eye on your change for any coins that
