@welshstacker I read your post last night then today went to have a look through a pot of copper coins that I have. First one 2p piece came out with New Pence on the back, "great" I thought, "what are the chances" then I came back and checked your post. Not so great after all, I'd forgotten the important detail of them being 1983 releases rather than the 1971 version that I pulled out!!
Ah well, I'll have to dig a little deeper...... still good info on your part though.
