If you look at ebay, you will find a whole host of offers on new polymer £5 notes. Those with AK47 series numbers are being offered at £1000 in one case and £500 in another. AA01 notes are avaialble for 3-5 times their face value.
The association with a make of gun is undersatndable, but how do more prices on more mundane serial numbers get set? Is it simply a case of 'try and see'?
On a slightly different tack, I wonder how much a set of three notes, a £5, a £10 and a £20, with the same serial number would be in a few years.
You are, quite obviously, not a collector.
If you take a look at the humble postage stamp, one with an priniting error can, at times, attract a price thousands of times greater than its face value.
Or, take a look at the prices offered for the so-called 'cherished number' number plates. MAG 1 C cost Paul Daniels £10,000+;
501 UP cost John Lowe £5,000+ and Paul Raymond, of softcore porn fame, paid a six-figure sum for UP U 2 and porn star Mary Whitehouse - yes, she changed her name to piss off the anti-porn woman - paid an undisclosed sum for PEN 15.
All this before the DVLA stopped the more suggestive combinations from being issued.
