It has active corrosion. Whether or not it has been cleaned is irrelevant given the corrosion. Also, I don't think you can tell from the photos...
Looks somewhat like a coin that went through a garbage disposal.
Slabs are not air-tight. And as @cpm9ball and @GDJMSP wrote, copper is reactive. There's the story (true) of the dealer who dipped a Peace...
Exactly right.
A lovely metaphor, and one to which I can personally relate, but it's totally irrelevant to the corrosion of metal. To the best of my knowledge...
WOW!V I'm amazed that members of this group don't seem to know that toning IS corrosion. Coins darken (= tone) because the metal oxidizes, which...
Your 1851 definitely has some wear. It would probably grade AU-something depending on how much luster remains. The 1854 looks a bit sharper to me,...
For those who are interested in learning about EAC grading, I recommend the book: Grading Guide for Early American Copper Coins, which was...
I once went to a half cent whist match at his house. Nice guy. This coin was from his collection, but I no longer own it. [ATTACH]
I think I see an 1805 dollar in there. That, alone, should tell you the whole bunch are fake.
The granite on which you put the coin is reflective. I would recommend a non-reflective (or minimally reflective) background such as a neutral...
Edouard, I'd say the photos are very good. They would be excellent if you could get the lighting even. Different coins require different...
What's particularly "impressive" is that their enhanced images also greatly intensify the look of the green corrosion.
The grade is completely irrelevant for a thing like this.
A few years ago, I did a study of the grading of large cents and half cents by NGC and PCGS as compared to the grades by EAC standards as given to...
I'd call the eBay coin AG and the Etsy coin accurately graded.
Lovely coin!
Vermont landscape coins have a reverse like you're seeing as undertype. There may be evidence of landscape undertype on the obverse, but I can't...
The obverse looks like the definition of VG. The reverse looks nicer, but you have to grade by the obverse. Nice coin.
