I'm convinced the coin has been cleaned- either with a cloth, or a very, very fine brush (the hairlines are not visible without magnification). From a grading perspective, this coin is clearly UNC details without any signs of wear.

I suspect someone was trying to make a nice AU BN coin into something that looked more like an RB/MS.

It's hard to make a call on value from these pics. If I saw a lot of hairlines in-hand, I might downgrade the coin (price-wise) to ~VF25--but that's just me.
