Found this in a roll the other day. Could it be an annealing error? For reference I included a pic of a slabbed specimen that I own (seller's pic) since my phone doesn't take very good pictures. In hand it looks like the slabbed one with the soft coppery coloring. Opinions?
I agree, the copper colored areas have a spotted nature and variation in color intensity that makes me think environmental damage. The graded example shows smooth and even copper areas.
Okay I'll go with that. Thank you. What in the environment would cause coppery coloring like that? Just curious so I'll know better if I come across another.
