I found this after a quick internet search. http://golddoubleeagle.name/1902-s-...gle-20-pcgs-fr02-lowball-registry-set-fr2.php
I once saw a 1907 high relief that the owner had taken a wire wheel buffer to half an hour before he brought it into the coin shop. BU/AU before, details F after. Made a collector want to cry.....
Was it the 1/4 where the COPY stamp had been? I've seen replicas where someone actually tried to do that...
