They say cash is king – but a rare coin from the reign of Queen Elizabeth II could be worth a pretty penny if you are lucky enough to possess one. According to one TikTok user with an interest in old and valuable coins, a 1954 penny has achieved an estimated value of £90,000 – and could fetch in excess of £100,000 when it goes under the hammer this month. In a video posted to his nearly 210,000 followers, user @CoinCollectingWizard gives an overview of the valuable coin, which is set to be sold under auction by Sovereign Rarities on 19 November.
