I recently acquired a few mint issued proof sets from 1959/62/63 and was wondering if it was typical/feasible/logical to have any of the coins graded. It's tough to tell condition of the half dollars through the cello but the 1959 seems to be the most spectacular. Anyhow, just wondering if the premium for a PF65/66/67/etc would justify cutting any out. Thanks!
I have cut out some of the more rare dates for submittal. On these I would keep them as-is unless you think you can get a 67 or higher.
Overall, with some exceptions, proof sets from the mid-50s to 1970 should only be graded if they are beautiful toners, or are Cameo or Deep Cameo. I don’t see either on your coins so I would keep them in the plastic.
The '59 looks like a FBL to me but it is my understanding that is not an official designation for proof strikes. The die polish lines on the '59 are DEEP!
