A rare Kew Garden 50p coin is currently being sold online for £120 with people - collector or not - being told to keep an eye out for it.
Speaking to Glasgow Live, one expert hailed it as a 'holy grail' coin as they are "pretty hard to come by".
So if you have one in your pocket, wallet, or down the side of your couch, you may want to reach for it and put it up for sale - or keep it in a safe place.
