Two £20 banknotes Prefix AK63 &AK68 with same number's 660076

I couldn't believe my eyes when I saw the number's. They both have the same number and same prefix of AK. At first glance the look identical. It was on closer look the prefix of one is AK63 and the is AK68.

Each has the same numbers behind which is 660076. The 6 at the of AK68 is a heavier print. The chances of getting the same numbers so close to each other you would have no fingers or thumbs left.

These are a collector's must all the way.
