Hello,
I am new to this whole thing and I have come across this 1992-P
Kennedy half dollar and I am told it is a proof and double die obverse.


I can see the
DDO. Specifically I took pictures of it around GOD:

the mint mark:

and the 9 in the date:

Am I correct in understanding this as a
DDO?
I can't see a difference in the proof section of the PCGS site here
https://www.PCGS.com/coinfacts/coin...images/96834 There are what I have understood to be a proof in that it has the mirror look. However, the one just above it is same grade, but the cloudy silver (like mine). Since this is clearly a P mint mark, and PCGS only shows the proof being an S, I am guessing I was told wrong about the proof part. Do I have that correct?
Last question: I can't seem to find any information on what kind of value I could be looking at with this coin. I know grading has a lot to do with it, but I can't seem to find another who has this
DDO (at least not from the P mint which is what I've been searching), so I don't know what I'm looking at. Only one? I can't be that lucky, but maybe?
A long shot, and I know I may be asking for the moon here, but could someone possibly have a rough estimate on a grade? I'm new, but was thinking a 58?
Thanks everyone!
