Overview
- Recent guides from a TikTok specialist known as the Coin Collecting Wizard have renewed public interest in spotting valuable notes featuring King Charles III.
- The creator estimates that very low serial-number £5 notes could sell for about £250–£500, with £10 and £20 notes potentially reaching roughly £500 and £1,000, depending on demand.
- The same expert says a small number of notes might fetch up to £5,000, which is a market estimate rather than an official valuation.
- Collectors tend to seek very low numbers, early prefixes such as AA or 1, repeating sequences, palindromes, and historically meaningful dates; the serial appears at the bottom right on the back of each note.
- The Bank of England says it withholds some of the first printed notes with low or symbolic serials for donation or auction, citing a 2020 sale of newly released £20 notes that raised a combined £143,420.
