So I just opened my first box of halves the 3rd roll I found this it looks like a proof coin is this a proof with accented hair ?
Can you please post a larger photo of the reverse. Thank you. https://www.bestcoin.com/1964-Proof-Accented-Hair-Kennedy-Half-Dollar.htm https://www.usacoinbook.com/coins/2878/half-dollars/kennedy/1964-P/heavily-accented-hair/
Still can't see the FG initials. Check your coin with the site posted by @cpm9ball or the posts I sent in my reply. All give the diagnostics to tell the difference between normal and accented hair.
It doesn't really matter that much. The primary diagnostic for the Accented Hair variety is the broken serif on the left-hand base of the "I" in LIBERTY. Chris
IMO the top photo on the left looks like it has the broken serif and the photo on the bottom left looks like it's not broken. That's why I asked to see an enlargement of the initials FG. (Because the reference sites use the initials as one of the diagnostics).
