I need to dig out my two (impaired) proof trimes and check - I have a PF58 and a PF50 to look at and try to photograph...
Yup... nice... just a few touches on the big star and the shield on the obverse and on the reverse the diamond at 9 o'clock, the leaves and top of the ribbon. Most important the fins on the big C are still slightly present. But I'm a hard case on grading these.
