I don't think it's FS-802 . The stars on 802 are split on the right side . And yours are split on the left side . Here's the link to NGC, where I got the images from . https://www.ngccoin.com/variety-plus/united-states/half-dollars/4740/816701/
I think it's either Coneca #2 or #7 . http://varietyvista.com/Variety Master Listings/kennedy doubled dies 1965-1966.htm Wexler site does have one listed . http://doubleddie.com/1607177.html
Sorry I shouldn’t have used that pic, I’m using my phone so it’s tricky to get all the splits to show up on the stars above the E P U banner. This pic is somewhat better.
I would send it to Coneca first, just to make sure you know which one it is . Pcgs will only slab cherrypicker coins, when it comes to varieties . What's the doubling look like on AME of AMERICA ?
Mine is on the left, right is the pic you posted from NGC. I think it’s an 802.. the doubleddie, wexler site has the die markers listed and pictured. Thats pretty much what I went by. I’ll do a side by side with the pics from that site too, in just a minute. View attachment 781091
