Depends on the carbine. There are ton of em that are so beat up they arent safe to shoot out there. There are also some commercial copies that arent worth anything.

The problem with being stupid is you cannot simply decide to stop doing dumb things...
It does depend on the M1 carbine's condition but also dont sell your SKS short either. The one I had was a damn fine shooter for a SKS. They can be upgraded and fixed up and in this economy and the issues we are having these days it has more value than before.
