In my experience, the only way to stop it completely is to completely remove the corrosion, strip the coin, and recolor/oil it -- and even then it...
I've always considered black "gunk" as verdigris, and the green/red "corrosion" as "corrosion". But perhaps I'm wrong. :rolling:
AU detals, cleaned, net XF. The color on this coin is all wrong -- they aren't bronze or CuNi.
The coin looks real, but has been overdipped/cleaned. That said, the vast majority of these coins have been mistreated, but personally, I'd wait...
Weakly struck AU 50 or XF 45 (probably higher graded, technically, but the weak strike does count against this coin, IMO). I'm sure someone's...
Looks like another 64 BN to me.
p.s. very nice '16, too!
Very real. :) http://www.coinfacts.com/large_cents/matron_head_large_cents/1838_large_cents/1838_large_cent_varieties.htm
Looks like an extremely fatigued die to me. Neat coin. I'd grade it 64 because of the obverse scratch.

Spock, Come to the toned side! :whistle:
IMO, it only pays to slab them above a value of $200.
p.s. VF 30 is what I thought PCGS would give the coin. XF 45 is a bit much, even for me -- then again, all we have are pics. :)
Worn smooth or lightly struck?
Nice coins, like the CBQ the best!
Here's something on this topic: [img] [img]
Please describe in more detail the "difference". I'd love to learn more about this topic -- and I'm sure others would too!
There are certainly worse examples around, but I think we're going to have to agree to disagree on this one -- this is a seller that I've been...
Looks like a TPG 63 or 64 to me.
Be careful! Some might say the same thing about a shiny SLQ -- or a nice piece of copper for that matter. ;)
