Reverse has vertical toned lines in all the fields. Haven't seen toning like this in hand before and was curious what is causing it? https://www.ebay.com/itm/166148849512?
Not sure what you are referring to. I see no "vertical toning" if this is the coin you are talking about.
I am not sure of the cause, but the reverse aging effect looks brushed on. The whole coin has a lot of weirdness going on.
I'm calling it fake. Notice the serifs on the C don't look like the real thing... https://www.pcgs.com/coinfacts/coin/1889-cc-1/7190
It's FAKE. It has the same mark in the eagle's breast, etc as the other CC fakes posted by @Jack D. Young.
Who the heck thinks they're getting a $10000 coin for $100? These buyers and sellers deserve each other.
I thought fake right away but decided to wait for Jack to chime in, among others of course. I followed my instinct. Thanks!
The stars are blobby, the letters are blobby, the denticles are uneven, everything else looks wrong. If you look at this and have any doubt that it's fake, you're not ready to shop for a raw 1889-CC. (I'm not ready to shop for a raw 1889-CC.) If you're aiming for a profitable flip, you'll do much, much better with lottery tickets. (This is not an endorsement of lotteries.)
It had become "Orange Hoody Time" when I got to it. If it was the piece that @Mountain Man man posted, it looks like some fake Chinese toning that they are constantly using. They have been experimenting with it.
