I'm fairly new here but I have had a few coins graded by PCGS. I recently had a coin graded and on the PCGS Site it was labelled AU Details - Damaged, then when I received the coin in the slab it stated AU Details - Repaired. I have looked this coin over under a microscope and had a couple of dealers inspect the coin and no one can identify anything that would remotely be a repair, damage, cleaning, anything suspect not even a rim bump. When I contacted PCGS I asked for an explanation of the grade, they don't do that. Well if this was a common coin I'd let it go but this AU Details or "N1" grade significantly lowers the value of the coin. Why can't the "expert graders" give the reasons for their reviews of any coin that they have an issue with?
