Message:: [QUOTE="Hobo, post: 311523, member: 11521"]Here are the answers to my original question: "Do you think these are NT or AT?" In my opinion they are ALL Artificial Toning. Here is what I base my opinion on: The toning has an unnatural appearance. It appears to have been brushed on most of the coins. Notice on the 1889 Morgan how the magenta (red) toning has 3 or 4 different brush marks. The toning in the fields climbs up onto and over the devices, numerals, letters, denticles and rims. With natural toning one color may be in the crevices of the hair (or numeral, letter or denticle) while another color lays on the high points of the hair (or numeral, letter or denticle). The toning on these coins is painted across the entire coin.  The rims are toned the same as the fields in many places. (That's part of the toning being carelessly brushed on the coin.) There is no gradual flow from one color toning to the next. There is an abrupt change from one color to the next. The color sequence is incorrect on some coins. The correct sequence for naturally-toned coins is Yellow - Magenta (Red) - Cyan (Blue). (See the Washington State Quarter.) The water droplets in the toning on several coins is an indication of liquid transfer toning (a process used by coin doctors). Natural toning is created by air transfer and does not leave water spots. The wild toning on the obverse of some coins is also on the reverse. That is not likely in natural toning.[/QUOTE]
