2014 'MULE' BRITANNIA ERROR £2 BULLION COINS
The Sun published an article this week on the “Mule Britannia” silver bullion coin. -Editor

A RARE £2 coin could be worth as much as £350 due to a small error made during the minting process.

There are thought to be around 17,000 of the “Mule Britannia” silver  coin in circulation and the defect which makes it valuable could be  easily missed.

The rare version of the £2 Mule Britannia coin is missing the  distinctive ridges around the edge – and there are 17,000 of the coin in  circulation

You can identify the coin by checking the front face, a portrait of the Queen, to see if the rim is missing dents.

Coin fans on eBay have been paying as much as £350 on eBay for the £2  Mule Britannia, according to completed listings on the auction site.

Although, some savvy collectors have snapped it up for as little as £60.

As a silver bullion piece the coins don't actually  circulate at face value, so the CHECK YOUR PURSE headline, while  eye-catching, is pretty useless. Of course, the numismatic details are glossed over by mainstream publications, who are often quite  late to the party. Here's more information from Jeff Starck's May 3,  2014 Coin World article. -Editor

Approximately 17,000 examples of the 2014 Britannia 1-ounce silver £2  coins were struck with an obverse die intended for the Royal Mint’s  inaugural Lunar bullion issue, celebrating the Year of the Horse in 2014. In addition, an estimated 38,000 examples of the Year of  the Horse 1-ounce silver £2 coin were struck with an obverse die  intended for the Britannia £2 coin.

A “mule” in coinage results when two dies not intended to be paired  together are used to strike coinage. The word “mule” plays off the  animal that is the offspring of a male donkey and female horse.

The Ian Rank-Broadley effigy of Queen Elizabeth II graces the obverse  of both versions of both coins. A generally tiny but significant detail  on the obverse makes the difference.

On standard examples of the Year of the Horse coin, no dentils are  found about the rim; the standard Britannia coin has dentils. All  Britannia coins are supposed to have dentils inside the rim on both sides of the coin, while both sides of the Year of the Horse coins  are designed without dentils.

The Royal Mint confirmed the existence of both error coins, though an  official did not specifically refer to either piece as a “mule.”  Calling the dentils “edge decoration,” Jenny Manders, a spokesperson for the Royal Mint, released a statement noting that, “Some  of our recent bullion customers may have noticed a slight change in the  design of the edge decoration of our UK 2014 £2 Britannia bullion coin, and the UK 2014 £2 Lunar bullion coin. ... The  quality and value of the coins remains the same.”

As with other mule coins, the value of the errors is considered much higher than the standard versions of the respective coins.
