My guess..somewhere above vf-30, but below ef-40. I don't think tihs group like Kennedy's much..might be why noone responded.
My guess is that they are both AU, but halves are not my thing. It would also help if the reverses were in focus.
Well, the 67 will be worth the silver value, and it looks to be in EF/AU The 1971 will not be worth a whole lot more than face, and might be VF/EF
