Genuine Nikkor or Nikon lenses are worth serious money.
Like a few others have said, take it to a reputable Camera shop and see what they say. If you need money, the "Ebay" market will find their true worth.

If you happen to have any wide angle, fish eye, or zoom/telephoto lenses and might be interested in selling, contact me via PM. (Photography is one of my hobbies, and I still prefer my 70s black bodied FE, to the digital format.)
