Ok, my first item is a 1967 penny that 'clacks' when you drop it. I COULD put a picture up but it looks just like any old boring 1967 penny! Nice grade, mind you, EF with traces of lustre, must be worth all of ... ooh, what shall we say, 99p plus postage? Could it be on a similar penny planchet but for another country? Is it a forgery made of another metal? (As if anyone would forge a 1967 penny ) Does it have anything wrong with the edge? It looks and feels exactly like any 1967 penny (definitely the right planchet, metal, etc). And you're quite right - who'd forge one of they? You'd only notice something wrong if you dropped it on a surface - instead of ringing, it clacks. The only I've not done is weigh it, but I don't have a set of they sensitive coin weigh thingies. I picked a little scales up off the net for £2 and a pound postage new, expecting nothing more than a rough estimate, but the beauty is accurate to 0.01 of a gram
