Most likely a die crack.
Perhaps, but under my 320x scope, this mark has three interesting features: 1. a clean, evenly radiused curve; 2. a consistent, sharp edge along the top of a near-vertical ramp from the coin field. 3. the mark ends in a distinctive micro shovel shaped point that is repeated in several raised, possible "skip marks" in the coin field. 4. Consider how the planar top features of the mark join to the more rounded shape of the feather (in the full-resolution photo).
I do appreciate your input--so perhaps you'll appreciate these pertinent details. And, for what it's worth...I've examined numerous die cracks under my scope, and they usually begin as a faint irregular line that at some point widens to an irregular mass of metal trying to fill a gap. Not quite as geometric as this particular case, I'd say.

This coin is going to Rick Snow for attribution--and I'll post the results to the forum.
