I would like some opinions on the toning on this one. Love it, hate it, let me know what you think.   |

I love it. I don't know why, but I enjoy the mottled toning.
I'm not an expert on types of toning and the way it forms, so I can't tell ya if it's real or not, if that's what you're asking.

I am not crazy about the toning. There are very few mottled toned coins that I favor.

I find it pleasing but almost certain proof of a coin recovering from an old cleaning. Whether or not it's "market-acceptable," I can't say, but I'm not optimistic.

I like it. I'd be interested to see what it looks like in 5 years.

Generally in silver/copper alloys Cu is about 5%. Along with Ag (generally blue) it gives you various rainbow colors. If you buy a coin which has been dipped - not brushed (hairlines) you can stick it in an oven say at 400*F and let the copper tone QUICKLY - bringing back some ORIGINAL color. Here is my merry-go-round response to your question. Its personal ... Initially, bare Cu metal atoms react with air to form the pink oxide, cuprite, Cu2O, which has Cu+1 cations. This gradually oxidizes further to the black oxide, tenorite, CuO, with Cu+2 ions. The black sulfide CuS also sometimes forms. In the presence of moisture, the blackish layer slowly reacts with sulfur dioxide and carbon dioxide from the air to eventually form the patina, which is a mixture of 3 minerals: brochantite, a green, hydrated copper sulfate, Cu4SO4(OH)6 malachite, the green, hydrated copper carbonate Cu2CO3(OH)2 azurite, the blue, hydrated copper carbonate Cu3(CO3)2(OH)2 In these compounds, copper atoms from the metal surface have been fully oxidized into Cu+2 (cupric) ions. The rate of patina formation and the proportion of the components depend upon humidity and handling. It does bother me when collectors tell me I only like WHITE. Never been to New Orleans in a TIME MACHINE in the 1800's and view the top coin in a Morgan dollar bank roll out of the bank?  |

Just curious from a guy still learning US coins - How does toning like this indicate that a coin has been previously cleaned? By the way, I like the toning. Paul Bulgerin

I'm a toning fan, so of course I love it. Given the high grade of the coin, I would feel better about it if there was luster beneath the toning; which would give me more confidence that the toning was not generated from a prior cleaning.

Yes ... toning ... PLUS ... the cartwheel effect ... not LUSTER.

Regardless of if it was an old cleaning or not I would jump on this coin for my type set. I think it would fit in well.
