From what it looks like, it is a sword that was made pre-aos with a lower mid level runic hammer.

If I remember right, whatever runic hammer was used, added the lowest possible damage bonus (15%) which was modified by an additional +10% at the time of the AoS change. The HCI was first included on weapons of increments of 2% ending at 10%, so that was lower as well.

My best guess is that weapon is a pre-aos exceptional runic made weapon.

The first exceptional damage bonus after AoS was 20% I think, because I have about a dozen of those weapons hanging around.

I wish I could estimate a value, but I have never seen any of those sold at anytime.

Cheers.
