If that color is accurate, I'd say that it is not PVC damage. PVC damage is sometimes called "green slime". Chris
Thanks. The color is pretty accurate I just snap photos and do a white balance check...no color editing. I have 2 silver coins from Curacao that I got from 2 different sources and they both have this green color to em. Must just be the way these tone.
Yup, that is just typical toning for these coins. The climate where they were used plus metal composition often results in toning that is uniquely recognizable for certain coin types. This is a perfect example of that.
It is not the most attractive toning, but it looks like toning. PVC can sometimes have a yellowish appearance, depending on the thickness and underlying metal. However, it is more often green colored. It will also appear hazy, like a film on the surface. What you show appears more integrated into the coin - like it's actually a part of the coin (this is how I would expect toning to appear).
