For most collectors of toners, this is not considered to be desirable toning as would rainbow, cat's eye, target, end-of-roll, tab toning, etc. The mottled obverse may even detract from it's value, so I would think it is only worth the value typically associated with an untoned Morgan. This is just my opinion. ~ Chris
I agree with the others. This coin appears to normally sell in the $65 range...and if that toning looks like that in person it might sell for a little less.
Agree with the assessment, likely lower price due to the unattractive toning. Unless you find a toned coin buyer that likes it. Good luck.
The unfortunate truth is that this coin, with obvious fingerprints and negative eye appeal, will trade at a considerable discount. Yes, it's MS64, and certified as such. Yes, it's naturally toned. But unfortunately that's not attractive toning at all. It's mottled and streaky and without any attractive colors. There's "good" toning and "bad" toning, and in my opinion, I'm afraid that's "bad" toning. Personally, if forced to choose, I'd rather have a professionally dipped white coin than this natural-but-unattractive coin. Opinions may vary, of course, but I suspect the majority would agree with my my unenthusiastic stance in this case. (But there will be a few folks who like this coin out there. Somewhere. Maybe.) The good news? It's still a Mint State silver dollar that's 137 years old, so it's gonna have some desirability, regardless. Edit: what I took to be fingerprints on the obverse might actually be textile toning. Regardless, it's still ugly, and I do still think it's fingerprints.
Then it's white and flashy, maybe... but cleaned. Not much point in cracking it out of the slab to dip it. Best to just accept it as-is, and keep the slab, or try to sell it to someone who doesn't mind the toning, I reckon.
It's not a totally unlovable coin. It just wouldn't be most people's cuppa tea, is all. Some folks maybe wouldn't object to the toning so much. It is original, after all.
