I saw this one reverse first, so I set up pictures in that order. A line reaching from the upper right wing to the banner containing e pluribus unum where the neck of the bust is. Slight curve connecting top of arrows to middle of right wing, line from arrows straight down.

I checked maddieclashes for the reference image (below) and couldn't find the "rhino horn" characteristic of JFK half clashes. Examination of coin in hand showed faint lines on his nose, so I knew it was a major die clash. Logical assumption: die was polished post-clash. I didn't notice until taking the picture that the die was polished enough to remove the bridge of JFK's nose.

And here's the reference image I had to double check on. It'll definitely help you see it.

Not as noticeable as a coin out of freshly clashed dies, but the coin forensic fun was worth it.
