UK households warned new King Charles £5 note could be worth £11,000

A rare King Charles £5 banknote has sold for £11,000 because of a small little-known detail. A banknote, which was released into circulation this month, carries the serial number CA 01 000003, which was a highly sought-after number among collectors.

It sold for an eye-watering £11,000 this week at a charity auction held by Spink and Sons. The auction also saw nine other rare £5 King Charles III banknotes fetch up to £7,000 - all because of the low serial numbers they posses.

There will be separate auctions held for the rarest £10, £20 and £50 notes will be held on June 27, July 11 and July 24 respectively. CA 01 000005 sold for £7,000 while serial number CA 01 000007 sold for £4,800 and serial number CA 01 000011 sold for £3,500.

Spink and Son said most people who buy these rare notes are usually veteran collectors who don't intend to resell them. nk of England Governor Andrew Bailey said: “We’re very pleased to be issuing the new King Charles banknotes.

“This is a historic moment, as it’s the first time we’ve changed the sovereign on our notes. We know that cash is important for many people, and we are committed to providing banknotes for as long as the public demand them. Bringing these new notes into circulation is a demonstration of that commitment.”

Karen Stonham, branch manager at Portsmouth Post Office, which is among the initial branches to stock the new notes, said: “Our local customers come into our branch every day to withdraw or deposit cash for their daily needs, so we were excited to be one of the first branches to have the new banknotes available.”
