I think this 2 cent piece is MS64 red. How about you? http://coins.ha.com/c/item.zx?saleNo=131147&lotIdNo=15001#Photo
I'm not expert in this series, but the coin looks "washed out". I would call it lightly cleaned over altered color personally. That said, it's a nice coin. I'd set it in a window sill for a couple of years to retone. I bet NGC would grade it after it retones.
I agree with NGC. Based on the uneven color it appears to have been recolored at some point, probably long ago based on the spotting that has since developed. Recoloring was not at all uncommon with older copper. Here's one I no longer have. I think it too was recolored so I never bothered to get it graded. Eventually I sold it on ebay, disclosing my opinion. It still went for a very nice price. Lance.
I agree with NGC. I would have missed the inside of the D, but the spotting is a big giveaway in these pics. I have a raw 1869 that I would grade 63-RB (close to RD). I bought it for $67 from a dealer friend who believed it to be recolored, but I disagree. PCGS will decide. Either way, I enjoy the coin very much and expect to make money on it when I'm done enjoying it. That coin may be a good opportunity for somebody on a budget who can live with the stigma of a "problem coin" for personal enjoyment (my personal collection contains many such coins because rim nicks, old cleanings, etc, are tolerable to me).
While I don't doubt that the coin has been recolored, I don't think that the discoloration at the D or the spotting or uneven color prove it. In fact, I bet that if the coin had been posted without NGC's opinion being included, many or most who have questioned it, would have given it a thumbs up.
I see nothing in the photos to suggest recoloring. That said, copper is a funny metal, and what appears in hand often does not appear in photographs. Therefore, I would tend to believe the experts at NGC who saw the coin in person over the experts only looking at a photo.
I would say altered, whether it's the coin or the image. In addition to spots, I also see too little contrast between the fields and the devices which seems to develop on even perfectly preserved, but uncleaned specimens. But I'm certainly not an expert on toning.
