Well I called the grade, but missed the corrosion. Tough call as I couldn't really tell on your photos what it was. Wonder if any conservation effort would help? Then get a clean grade, possibly at PCGS where the value would increase a lot more. Super coin, I'm glad you got them back without any incident!
