Only costs £45 for an old fiver...

Well I've just done some research and now I'm rather baffled.

This claims to be a "first run", which does indeed make it a more valuable note. However, the first run should be AA, not just A. There should be 4 digits at the beginning, not 3.

Beale told us that serial numbers are one of the key indicators of a rare or in-demand bank note. Many collectors prize the first notes in a series, although other types of note are also popular. Bank notes are printed in sheets, with a serial number on each note indicating the order of printing. The two-letter prefix at the start of the serial number is changed to AA every time the design of the banknote changes – so, for example, the first batch of notes printed is always numbered AA01. Any note from the AA01 batch could be of interest to collectors. The first notes from this batch are often presented to dignitaries, meaning it’s rare to see them in circulation – for example, serial number 000001 is always presented to the Queen and 000002 to Prince Philip. In September, auction house Spink will sell off a Scottish note with the serial number A01 000001 to the highest bidder. The note is valued at around £2,000-£3,000. It’s extremely unusual to see a serial number below 30, according to Warwick & Warwick, and any number lower than 200 is likely to attract high demand. In 2012, for example, Spink sold a £50 note with the serial number AA01 000200 for £220

I have checked images of old fivers and this system does seem to also apply to them too. So this particular note is either fake, or it has a typo, which would make it exceptionally more valuable, way more than £45!
