Yes but... here are a couple of cases in point. Both of these were fresh out of a sealed 1970 set. Neither qualify for FDC in my view, and in point of fact, left the mint that way, the first because it's got a couple of minor scratches on the bust and the second because some bozo at the mint has stuck his thumb on it! If these were not proof, you could still describe them as Unc, the first for the reason that 'bag abrasions' are permitted, the second because toning doesn't affect a coin's uncirculated status. But as proof coins, they don't as I have said qualify for FDC, 'uncirculated' goes without saying and really doesn't help us much, GEF implies some wear which they patently haven't got and I really don't want to go down the route of calling them AFDC because that is utter gibberish! So what do I call them? Perhaps I ought to get out more... Maybe we should just go back to the old-fashioned way: Impaired Proof. Proof with a pawprint. Proof with a scratch. Maybe only allow one grade for Proofs - FDC, and everything else just gets a description, unless it's got proper circulation wear, in which case it can go into the normal system. Not very smart commercially, of course - may as well consign them to the "Will never sell" bucket!
