A few years back whilst working in East London the elderly lady cleaners used to sell them (about 40p each). (Together with Baccy,fags and cheap spirits.) I can remember getting a few in my change during this period. I put them in my money tray at home which was then raided my the Missus and spent obliviously at M&S. Personally I would be more worried about buying forgeries of collectable coins. I'm still looking for a decent 1775 1/2d (although forgeries from this period are now collectable in their own right). I've got a few. I was aware of rumours surrounding forged 1905 2/6's...has anyone come accross these....now there is an idea...knock em out for 40p each.
