Hello US collectors, What is your opinion on the effect of a scratch on the value of a 1907 Saint-Gaudens high relief wire rim $20? The coin is in an NGC holder and was deemed a UNC details due to a small patch of scratches on the reverse between the sun and eagle. It's easy enough to estimate the value of a straight-graded coin but sifting through sales archives for Details-grade coins is challenging. From what I see, not all Details-grade coins are equal. From what I glean after searching archives, some problems are worse than others. Improper cleaning seems to detract less from the value than do scratches, or at least that's what I found based on limited research. I realize there is not going to be a one-size-fits-all answer, but what are your opinions about scratches on an otherwise desirable high grade Saint-Gaudens? All opinions are appreciated .
