Will, you can strip it and it'll be worth more per pound. But, for the time it takes vs the benefit, I don't think it's worth the trouble. You might try stripping various sizes of wire to get a feel for what's worth stripping. I strip the heavier gauge stuff - like house wiring.

Stripped - it'll be #1 or #2 copper wire
Unstripped - it'll be "Insulated Copper Wire".

Look at prices for each.
