It’s all well and good having the coveted Jane Austen £5 note worth £50,000, but what about the rest of us who don’t?

Fear not, Daily Star Online has been in touch with banknotes experts across Britain to find out how much all your fivers are worth.

Even if you don’t have the craved “AA01” prefix etched across the corner of the polymer note, we’ve found you could still have a small fortune in your pockets.

For those of you who do own one of the first million (AA01) £5 notes, they are worth £50, according to Simon Narbeth, of specialist paper money dealers Colin Narbeth.

But if you are really lucky and have an eBay account, you could sell it for as much as much as £500 on the buying and selling site.

If you find your AA01 domain followed by a serial code in the low digits, you could at least double your money.

Andrew Pattison, of Spink - an auction company specialising in banknotes - told Daily Star Online: “The lower the number is the higher the value.

“Any notes with numbers lower than 001000 attract a big premium and are likely worth £100 more.”

Beyond AA01, if you own a fiver with any of the following prefixes ending “01” you could pocket nearly double the face value.

Those worth £15 are AB, AD, AE, AH, AJ, AK, AL, AM, BA, according to Pamela West, an expert at British Notes.

But it is the notes with "block serials" you want to look out for, which Andrew says could fetch you around £300.

“If you are lucky enough to find another type of interesting number, such as a block number (111111, 222222, 333333 etc) or a running number (123456 or 654321 etc), then these will attract a premium regardless of the prefix,” he says.

“These may be worth something even in poorer grade. The number 8 is particularly popular in the far east, where prices for ‘fancy numbers’ are highest, whereas the number 4 is unpopular. A block 888888 can expect to fetch several hundred pounds in nice condition. Even other strange numbers like 080808 can be sought after.”

Pamela of British Notes agrees, and also says "ladder serials" such as 123456 are also worth keeping an eye out for.

Another prefix that has proved popular on eBay is AK47 - also the name given to type of machine gun - but experts believe these to be worthless.

Pamela told us: “As for AK47 there are a million AK47 notes printed, thus, no shortage!

“It is just a fun prefix.

“Hundreds of people have tried or do try selling in online auctions, some have been lucky, others not so.

“Some purportedly high prices have been achieved, but, are they actually paying? or just playing at bidding?”

Andrew says: “Novelties such as serial number AK47 are not currently even worth more than £5.”
