Here are some photo's of my latest Morgan Dollars. They have some incredible toning. The first is an 1883-O with incredible Obverse emerald green and burgundy to purple toning. She cartwheels like a gymnast. I shot it using axial lighting to show the toning. This style of lighting mutes the luster and it appears very flat. But trust me the luster is there in spades. The luster turns the greens to a lovely cyan and cobalt blue when you hold it and turn it in the light. The reverse is an incredible champagne gold with a little magenta a peach mixed in. I bought these raw and am considering sending them in to get slabbed. Here is the first one. I'll describe the second in a moment. The second Morgan is an 1887-P with beautiful golden peach to rum and whiskey tone around the rim. Again she has very beautiful luster which is not visible in the following photo's because of the lighting technique. The reverse is somewhat similar to the obverse but the toning is more muted. The reverse has some nice light golden toning with some parts of the fields a light cyan silvery color with some of the rum color out near the rim. Here are those photos. So do you think they would be worthwhile to send to either PCGS or NGC? I'm into the first one for $55.00 and the second for $45.00.
I'd send in the 1883-O, but not for the reason you might think. Either that, or sell it. The cobalt blue you mention will eventually turn black if you don't slow the toning process. Slabbing it is the only way I know to accomplish that. If you're wondering how I might know that, it is because I had two very nice '84-CC GSA Morgans in the OGP that had cobalt blue over 50% of the obverse. They were graded MS64 by NGC. It only took a few years for the cobalt to turn black. Chris
Its a natural process when metal is in contact with atmosphere. See below http://www.coinnews.net/2007/09/03/...ow-does-it-affect-coins-and-their-value-3565/
