A sightless person should have a well developed sense of touch, and the ability to read Braille. I think if they ran a finger over the surface they would note a smooth area free of palpable defects compared to the edges of the field. This might be interpreted as smoothing of the area.
I'm not trying to be funny but I've read 3 pages on this thread and so far I haven't learned a single thing
My answer to a coin like this is that it's been messed with. I believe that at one time, some parts of the field were much darker. Some spots were probably removed.
You are right. Wise advice. I was just a little miffed, and insensitive, because my feelings about time were hurt, having to wait 24 hours + for an answer promised in one hour. I will try to be more patient and wait, and just rely on Thoughts and Prayers....
I read the whole thread yesterday as well hoping someone could outthink me on how to explain color changes to a blind person. There were a couple of thoughts/theories that came to mind, one being temperature where light would be warm and dark being cold, the other theory would be texture as in hard and soft. I concluded the best explanation would be a combination of both as the edges between the mottled dark and light colors are not crisp/hard but instead soft and mixed. The same as one would expect with a chemical treatment dropped onto the surface and wiped around having more concentrated areas of the chemical. I suppose polishing could also produce the same effect as the tone of the surface is worn through in a more heavily polished area.

I became completely absorbed in researching a AG-3.8 double struck colonial to see if it was Machin's or British that I completely forgot about CT. paddyman98, posted: "I'm not trying to be funny but I've read 3 pages on this thread and so far I haven't learned a single thing." That's possibly because you are considered the "resident ex-pert" in this tiny part of the Universe. You just made me feel like I wasted a lot of my time. Wait, I shouldn't feel bad because this thread may help others who are not as "talented" as you are. longshot, posted: "The area has been buffed for some reason...I'm not convinced this coin is genuine....there are pimples on the leg that leave me with questions." "Pimples" on a small portion of a coin are not a sign of a counterfeit. That'can be the topic of another discussion. Hommer, posted: "I read the whole thread yesterday as well hoping someone could outthink me on how to explain color changes to a blind person..." You are correct. I forget some folks are born blind. I should have said a 40YO experienced dealer who just went blind so they would understand color. The entire point of this exercise is to get folks to develop a DETAILED description of what they see to a person who cannot see the coin for any reason. Answer: You were given two clues that may have been helpful to some members. The coin is a Trade dollar and the dark stain has some distinct form. T$ are often found with repaired "chops". They are usually easier to detect when the field is repaired rather than a masterful reengraving of the design. Remember that a coin's color is very important when looking for repairs, improper cleaning, counterfeits, and alterations.
Do your recall if there was some counterdamage on the rev, opposite the chop? Interesting case. I don't recall seeing a Trade Dollar with a repaired chopmark before; maybe the label just says "repaired" or "smoothed" so I didn't look any closer.
Lady Liberty only has 4 fingers... The dark blotchiness in the field below the branch looks like it may be some kind of design, perhaps? I'm not sure. Or the coin may have been improperly cleaned at one time. That's what I'm going with.
I don't remember. Usually there is only a very slight "flat" opposite many chops because the entire coin absorbs the punch; however, with some deep chops the coin actually rocks a little because of a bulge on the opposite side of the mark. Manny, Good observations; however, you are a little late to the quiz. Go to page 1.
