[QUOTE="satootoko, post: 30204, member: 669"]Those statements are contradictory. The first one [i]is[/i] the definition of the term. On the other hand, a grade is an assesment of the condition of the item at the time of grading. Any manufacturing [U]process[/U] can [u]result[/u] in artifacts with a wide range of quality. The resulting artifacts can then be subjected to an extensive variety of post-process conditions, abuses and environments. Therefore, a coin produced by the proof [i]process[/i] can easily [i]appear[/i] at some point to have the visual characteristics of anything from a P0 to an MS70 DCam. That's why high grade proof coins are graded "PF" instead of "MS", and any proof can earn [i]any[/i] number on the Sheldon scale, including a hypothetical PF/P0 after sufficient abuse :eek:, such as giving a gold proof a lengthy dip in aqua regia. :mad: :eek: :mad: Nothing personal catman - I'm attacking your conclusion, [b]not[/b] you. :D[/QUOTE]
