Moving my set from Whitman to Dansco albums, this quarter is originally from a mint unc set. Obverse, mostly on the right side, showing horizontal lines, or trails, from much of the lettering. I looked through Mike Diamonds Error-Ref.com site, appears to match the description of Defects Related to Die Polishing, Trails and Wavy Steps - or maybe just another type of die deterioration?
Yes, die polishing. I was schooled on this subject recently, too…trails. Nice looking coin notwithstanding.
