Same on the reverse,devices arent touched at all when you can clearly see ,if it were wired,they would be.
I don't know about that quarter but that isn't what this thread is about. We are discussing the 1964 cent so I'll start here. I wish the cent pictures were better an more of them close up. This to me is what I would expect aggressively intentional die abrasion lines to remove clash marks would look like, and compares roughly to 1966 and 1967 aggressively intentional die abrasion coins i've seen, although theres usually more abrasion around the device edges and a softening of those edges from it, more i line with the top of the 4 where it appears stretched some towards the rim. However, I don't know of any clashed die example of a 1964 Philly cent, I haven't seen one to be able to say a clash happened at Philly that year. Possible they clashed it and went to abrading it out before striking anything with the clashed die pair. I think if that is intentional die abrasions done manually, then it would have to had been something pretty severe to require the whole die abraded by hand and both of them of the pair. My problem is this isn't entirely what I would expect to see from an abraided clashed die with more work around the rim and across lincoln where the memorial would be, my clashed more than once and it rotated between clashes requiring the whole surface to be abraded harshly???? Nothing happens until it happens right. LOL. I'd think if the Kitty has multiple examples with the same scratches, an explanation for the scratches seen in the picture would likely have to be localized, die damage, maybe like a tool hit or a strike though that wasn't a clash but damaged the die requiring it to be abraded to make it look better. Who knows maybe someone dropped it on the floor face down when they were installing it and thought to hit it with the abraider real quick to try and work out the dings to the die. the lines would disappear after a couple hundred strikes I'd think tops. the video in this thread is a die polisher, not an abraider. it's a much finer pad to polish the dies smooth, like a buffer, the abraider would be more like a grinder, or dremel you wouldn't use a grinder to wax your car, and you wouldn't use a buffer to grind corrosion out of your wheel wells on your 1967 firebird 400 rebuild you'd be doing it for the next week or longer if you did. hahahhaa.
