Stripping Copper Wire

I was just wondering since I never tested it. Since insulated copper wire is $1 a pound and copper wire that isn't insulated is $2.50-$3.20 pound, is it worth stripping.

Say I have 5 lb of insulated copper wire. That's $5 now if I strip it I'm losing the weight of the insulation but being payed more per pound. If I lose 3 lb of insulation then I'm only getting $5-$6.40 for the 2lb of copper and I was going to get $5 to start so it wouldn't be worth it.

Any info/tests you've done would be helpful. Thank you.
