I was just about to list a half-decent 1928 halfpenny for sale but couldn't find any others for sale on dealers' lists or on eBay. Never had this pegged as a scarce coin but possibly more difficult than one would expect?
For interested Penny collectors, I have included details of the new obverse along with many other rare pennies, on a new page on my website, entitled "Varieties That I Don't Have" (but fiercely covet !!!!!) Richard
