I know it's a bad idea to open a proof case, but I did it for the half dollar. I usually have trouble handling proofs, should I send this to PCGS to get it graded and sealed? P.S. You don't need images. It looks like any other 1970-S half dollar proof.
Without photos I don't believe anyone here will be able to give a decent answer. There is a huge difference in prices on this one, starting at $10.00 in PF65 all the way to $350.00 in PF69 DCAM.
Based on the price of grading and the values assigned by PCGS, I'd say no. Now, if you are absolutely sure that it will grade PR70DCam, I'd submit it. Is it a DDO?
