1963 Lincoln Cent - Gorgeous Shape But. Issues?

Hi gang. I came across this surprisingly clean and bright 1963 Lincoln Cent in one of our change jars.

I scouted the forums to get some reference on condition and color (R, RD,B) others submitted. I'm too new to consider myself objective aside from the obvious that it's in fantastic shape for a 58 year-old penny and would love the forum's take on it. I also wanted to say (since it's not so obvious from these pics that the steps of the memorial are tight, un-marred or dinged, and very well defined. Aside from its shape, I included another shot that better highlights the ghosting on the reverse of Lincoln's bust from the obverse. Don't know if that helps or detracts from the general condition/grade.

Additionally; after seeing another post where someone pointed out their 1963 penny's width maybe flagging it as a proof, I held it up against another well preserved find from the same change jar, a 1964 Lincoln Cent. That raised another question as I noticed that while the 1964 cent's width was pretty uniform all around, this 1963 Cent's width varies quite a bit - from same width to obviously thinner, and although the penny shows no sign of "trauma or impact", at one point, it's width is wonked enough that you can actually see daylight between the two. Again, it raises the question if this helps or detracts from the overall grade of the coin - or if it drives it into a question better submitted in the "US Modern Variety and Error Coins" forum.

As always, thanks for everyone's insight and knowledge - any light shed is good light and always appreciated. Have at!
