Hi everyone.
I was looking at my (way incomplete) set of Walkers to practice some principles of grading that I'm learning. What I was trying to do was to see if I could determine whether it was a good or bad or medium strike. So I was looking at two coins, roughly the same condition (Fine, maybe low extra). Anyway, the strike on both coins looked similar, but one coin was much dirtier than the other. Ironically (?) the grime on the dirty coin gave the coin more eye appeal because it collected in such a way as to emphasize the contours of the devices on the coin, like shading if it were a drawing. Since it was such a contrast with the relief, the relief stood out that much more. The other coin was not as interesting. Maybe, thought I, the dirtier coin was more fully struck than the other. Anyway, is this a common phenomenon everybody knows about, and/or does anyone have any opinions on the subject?
