TikTok user @CoinCollectingWizard, who has over 200,000 followers, is urging people to check for rare King Charles III banknotes, which began circulating in June. Notably, a banknote with serial number CA01 0000003 is valued at around £4,000. Collectors are particularly interested in notes with low serial numbers, as they may fetch high prices, with some estimates reaching £20,000 on platforms like eBay.
