Yes, gold can have verdigris, silver can too. But that is not verdigris, that is remaining dirt and grime left on the coin after it was harshly cleaned.
Good news/Bad news ThanX, Doug. Guess that makes it Good news/Bad news. It means it may be real, but dirty gold. Since it is already ruined I'm thinking of dipping it. ThanX again.
Bang! I didn't post a photo of my bullion in the other thread, Doug. I understand. This was just an extension of the same problem on a different object. :high5:
No it cannot unless there's copper impurities in the metal. By definition, verdigris is a copper containing compound. Gold and silver complexes/compounds are corrosion and NOT verdigris.
Exactly EXACTLY (& I normally hate that word) But many relationships ended with the GREEN showing up. And at first this had a green tint to it. But that could have come from what was next to it. And I know it has been "below the water line" more than once. Since it is "Damaged" I intend to ruin it until I like it. I noticed I can blow up the op image A LOT. (Dang~I cut roses down last weekdd
And what US gold coin do you know of, and not the modern bullion issues, that does not contain copper ? Thus my answer.
...hum....book sez:.90 gold/.10 copper....... So I may have bad mix planchet and therefor a dirty "Golden Woody"?
Don't misunderstand DOK , I was in no way saying that your coin had verdigris on it. I specifically said it did not. I was merely saying that gold coins could have, and sometimes do have, verdigris on them.
We just need to be sure not to confuse people. When you make the verdigris statement, you should follow with it's due to the copper and NOT gold or silver.
Got that the first time, but thanX. As you have often said~ "As I have often said." I'm just making one last pass through before I decide on where to start. It's just that this & some stuff next to it first saw the light of day as Greenishness. Oil or Vinegar~ Heck, I may just chuck it into the Christmas salad and let another family member have a go at it.:bow: ....nawh...pshaw....I want to practice on this one myself.:eat: I believe you.
To me that mark appears to be where someone removed solder.... The dark areas on the left center of the coin to me at least appear to be remnants of the solder that weren't removed... I would also make sense because it's in a circular pattern in the middle of the coin where I see the most solder on gold pieces... The center of the shield seems to be "missing" for a lack of words... to me also indicative of removed solder... not to mention the $2.5 is a popular size for jewelry. Just my guess.
You do indeed see a lot, LD.:bow: It was in with jewelery in a cigar box. I'm going to start with plain water and hope. I'm not frustrated enough to try solder wick & heat.......yet.
This is common on gold pieces from the era. It was a jewelry piece, and what you see is solder remnants. If you look at enough gold coins, you'll find many of these. Most are more damaged than the coin you show.
