Can anyone help me determine the value of this gun? I got it 15-20 years ago and it is in like new condition though has been ported and has a kick Eze butt. It is 12 ga with the walnut stock. 28 inches. I looked online and saw cabelas and gander sell the gun for $999 but realized it is not the super 90, I guess mine is no longer made. Having trouble determining value want to sell to a friend and be fair.

Don't know how to post pics
