Found 3 of these with the identical error on the eyebrow. Is it a die crack or a strike thru error???   http://s149.photobucket.com/user/hurricanedude/media/20190306_153040.jpg.html?sort=3&o=1

It appears to be a lint impression, which is a subtle form of strike-through error.

Thanks... I was thinking that since it wasn't extended into the rim of the coin. I have many proof die cracks that seem to originate from the rim of the coin inward towards the center..
