The so-called CoinCollectingWizard has been sharing his wisdom with the public, and now, he has explained why you should keep an eye out for a 1952 'proof one penny'

This coin is among the "most expensive" and rarest coins in Britain, an expert said Brits have been urged to check their old jars of coins at home for a specific penny that could be worth a whopping £127,

However, only those dated 1933 are worth a lot of money now so you need to make sure you check the date. This is because there was low demand for penny coins that year with some of the few produced in 1933 placed in the walls of buildings or given to museums.
