Is This Bronze Disease?
« on: January 19, 2023, 07:11:43 pm »
So, I was photographing some coins to put in my gallery. Here is one that I recently got in a lot. Are those green spots bronze disease? I have never had a coin that had it to my knowledge, but this one worries me.

Thanks,
Virgil

Does the green flake off easily as a powder with a sharp wooden  toothpick?

If not, probably not bd.

Thanks, Ron. It does not easily flake off. Possibly traces of old patina or encrustations, this one looks like it may have been fairly harshly cleaned.

Bronze disease is like dust. If it is bronze disease, you can easily brush it off the surface, or pick it out of a pit. Unfortunately, it comes back quickly. Coming back is the real confirmation.

Thanks, I don't think it is BD at this point. It does not come off easily.
