I was thinking that but starting looking at the lighting. It's been a while but I remember the problems I had trying to image dark copper. My images always turned out too bright or too dark.
I don't have much experience with copper after the 1820's, but I am pretty familiar with how early coppers up to that date should look like. This one looks certainly different to any of my early coppers. That is why I was asking.
I think it has original surfaces. REASON: All of the debris around the devices, particularly on the reverse.
Wow.... I been looking at old coins a mighty long time. I swear I thought this was an illustration. Not a photo image. Time for me to throw out the three dollar readers and go see the eye doc.
It is a nice chocolate. However, the rim is a different color than the rest of the coin. Both sides. Is it the lighting bouncing off the rim?
It sort of looks it has a flat (not matte) brown-anodized finish; recently manufactured, almost. You don't usually see such an old metallic object with such a uniform finish. My devil's advocate two cents worth.
Whilst I agree it’s possible it was cleaned long ago and has since retoned, I think it looks great. I don’t believe acetone will have any effect - positive or negative.
