Probably not, but gotta ask anyway. I do not own the coin, but I am considering purchasing it. As one member of the "Fantastic Four" says... FLAME ON!
If by "conserve" you mean returning it to anything near a no problem example, of course not... but if having it worked on (doctored/restored) to a more presentable state, it could certainly be "improved" upon. Is this one worth the time, effort, and money? No....
Appears to be a residue rather than corrosion. It looks like some of it has already chipped off. If it can be removed, it will leave a shiny area for sure.
The coin has already been cleaned, so there is no turning it into a no-problem coin. I would stay away from it.
Thanks for "heads up" guys; but I don't know any more than the next member. DON'T BUY THE COIN. If you cannot resist making a big mistake buying someone else's problem, that looks like a hard rubber-like encrustation. NO TELLING what's under it. Looks like it is hiding a repair. First see if it is a soft (hopefully) or a hard deposit. Push thorn or SLIVER of wood into it to see. Let us know what you decided.
The whole area of the left field behind the head has been tooled/smoothed and then "hidden" by that gunk. It also looks like a repair job has been done on the reverse to the left of the tailfeathers. In my opinion it's worth maybe $100 or so.
No, not websites...just this one. Besides, I'm not monitoring it....I'm participating. I often wondered how many chat on websites and trolling the web while at work and getting paid by their employer. Unless of course, this is your career.
That dark crud looks like it's hiding something. The surfaces in that area look tooled too. And the coin has also been cleaned and has the dead unnatural surfaces of a cleaned coin pass at any price
So, if you work for the government, that means the taxpayers are (indirectly) your employer.... Get back to work.
Change can also go from the bottom up. Speaking of bottom(s) up...it's Happy Hour down the street in four minutes.
