Grade opinions on 1971 DDO pt. 2

[admrose]

Here is the other 1971 DDO # 1 I found, also an LDS. I'm not too thrilled with the spot on the obverse but otherwise I'm thinking AU. Opinions welcome.

AU details - corroded and/or active PVC. You need to soak that coin in acetone. I am pretty sure that is active PVC below LIBERTY.

I agree AU. Acetone won't hurt just in case it is PVC, but it looks like garden-variety verdigris to me. VC should take care of some it....and maybe all of it.
