Genuine Undated 20p Mule Coin (open to offers) -

I have a Genuine Undated on both sides 20p Mule Coin in excellent condition, Please feel free to make me an offer above 100 and I will contact the highest offer. The London Mint Office bought back 15,000 for 50 and 10,000 for 100 so 25,000 have been removed from circulation so they are becoming rarer. This is a good opportunity to own a collectable Royal Mint error coin. In November 2008 a number of 20p mule coins were incorrectly minted resulting in their having no date. This problem affected less than 50,000 coins of the 136 million 20p pieces minted in 2008-09 and was due to the previous obverse (the ‘Heads’ side) being used with the new reverse (the ‘Tails’ side) design, meaning the year of issue did not feature at all. These coins remain legal tender and still have a face value of 20p.
