I picked this up a long time ago raw and can't even remember why I sent it into NGC. I picked it up because the detail on the coin is really good for 1925 S peace. It's so hard to find detail on the eagle and on the hair for that year from that mint. My question though how do you think the coin was cleaned to make it look the way that it does. The fields almost look mirror like. Is it polished? Do you think its retoned or is it a byproduct of the cleaning process that the person used? I really am just wanting to understand the affects of cleaning more. Usually they look washed out or you can really see the tone around the detail in the corners and crevices. Or you see a ton of hairlines which I really don't see on this one. I need to put it under a scope.
I'd check with a loupe - 5x and then 20-30x. If you don't see prominent hairlines, my guess would be that it has been dipped excessively, permanently altering the surface. It then may have retoned somewhat. I'm curious what others might add. I'm still learning here.
From your photos I do not see any lines so I’m leaning on dipping incorrectly. If this coin was over dipped it would be a shame.
