Hi, Here is my raw, 1902 Indian Head penny. To me, it looks great and has this orange glow to it. When I look at the PCGS website and GC archives, I see slabbed coins in the high AU range that look similar to this one. I don't see an obvious cleaning marks, but I am still l learning. I'd be interested in if you think 1) it has been cleaned or not and 2) what it would be its worth in either case. Thanks!
I don't see any immediate signs of cleaning. The darker areas you see are a bit of wear and toning from circulation. I agree with your AU grade, and would probably put it around $25 - $30 range.
