For many Brits cash is no longer king and any unwanted shrapnel is quickly chucked into a charity box.
But a coin collector has urged Brits to check their change jar or they could risk giving away a fortune.
If you own a 1933 1p coin you could be sitting on a cool £140k.
Records indicate that only six coins of this type were ever produced – with three being laid under the foundation stones of buildings and the other three handed to national collections.
However, The Royal Mint says there is a chance of another being made, increasing the total to just seven ever produced.
A statement about the rare coin on the organisation’s website reads: ‘The 1933 penny is one of the most famous coins from the UK.
‘The Royal Mint’s records refer to six being struck, three to go under the foundation stones of buildings and three to national collections.
‘There are, however, good references in the Mint’s records to possibly suggest at least one more had been made.
‘As this was an ordinary circulating coin, it might have sneaked out into circulation and people would actively look through their change prior to decimalisation in the hope of finding one.’
In July, one coin collector spoke about the coin in a video on TikTok after being lent a fake copy of the item to highlight its value.
Posting to their 196,000 followers on the social media platform, @coincollectingwizard said: ‘This is my private collection, featuring one that’s been loaned to me very kindly. It’s great because it’s such an iconic coin, so we get lots of visitors coming to see it.’
‘Usually these coins disappear into safes and are never seen again. The last sold in 2016 for a hammer price of around £140,000.
‘Its first ones had sold for many many years and one would imagine if it would come on the market again it would sell for even higher.’
‘This is the 1933 predecimal penny from the UK, so make sure you check your grandad’s old coin collection and keep an eye out for this date.
‘Now obviously I don’t have the coin, this is a fake copy version.’
