Hi. I'm new at this business and am going through a small collection left to me by my grandfather. Most of the stuff I can work out using the variety of sites on the net. I have found a George 6 thrupence with a George 5 coin inside it. The George 5 coin is like a current one pence piece with Georges head on it. There are no dates on either side. Does anyone recognise this description or has my grandfather hollowed out a thrupence and stuck another coin inside it. If he did, he did a very neat job. I'm sure you guys will know what this is. Please help me out. Ta much,... Jeremy
