Bare wire is worth more as scrap than wire with the insulation left on it. If you can get quotes on the value of copper and what you might receive with the insulation left on. A little elbow grease maybe worth your while.
Steel, aluminum, lead, zinc and most other metals all have value as scrap metal. Make a few calls to receive an idea of fair market value.
