[QUOTE="physics-fan3.14, post: 3195640, member: 19165"]It graded because, although it is *highly* unusual, it also looks perfectly natural to me. The color progression from light to dark looks absolutely correct (which it often doesn't on an AT coin). The "elevation chromatics" also look correct - the tones are different on different parts of the coin, based on how the air would have flowed across the coin. For great examples of this, look at how the color is different in the field between the eagle's tail and the rock, or in the low spot at the bridge of Liberty's nose. These aren't 100% foolproof methods of determining NT, but they are hard to fake. Given the AU grade, I strongly suspect that this coin was picked up by a collector shortly after it was made and then stored for much of its life. I don't think it was an album, based on the appearance of the toning, but it may have been some sort of envelope. I also see zero evidence of improper cleaning, [USER=28531]@H8_modern[/USER]. I agree that residue left from cleaning may lead to unusual toning, but I don't see any evidence of hairlines or polish in these images. While this coin is extremely unusual in the vibrancy and completeness of color, it also looks quite natural and incredibly attractive to me. I'd buy it, but a coin like this will sell for an insane premium.[/QUOTE]
