Original tail lights question

[jumpman420]

Hey guys and gals. A while back I picked up some twilight lenses that I believed to be for the cobra. In original NOS boxes, not in the best of shape, but still there. There are 3 lenses and 2 metal surrounds in 3 boxes, two of which are the same, lenses and surrounds and a separate designed box with the single lens. I have had them authenticated with an original cobra owner locally, who basically told me they aren't worth anything to most people and even original owners wouldn't pay anything for them because there is no market for them other than for original car owners. He isn't a very liked guy around the area, because he is very wealthy with daddy's money and his old cobra and expresses this usually how he is better than most people. Long story short, I'd rather throw them away than give them to him. Question is, what are they worth? Second question, is there any interest on here for them? Thanks much in advance. Look forward to hearing what your thoughts are.

Also, is there any way to identify valve covers from original cars?
