Great. At least we can say we know what it is now ! Are they quite common ? Not common as in coin-common, but not rare either, and with only a small collector base anyway. To be honest, yours is too worn to be of any interest more than scrap value ... but I've never seen a worn example before! So it's interesting purely from that perspective. Thanks for everyone's comments & info. They have been much help to me as I will admit to being a complete and utter novice! Shame they are not worth anything but still interesting items. I did take pics of the four pence but unfortunately they wont upload I must admit I was looking at the four pence thinking it looked more like a man on the head side!
