If it has an o our a c under the eagle you could get it for around 15-30 $. If its that and in marvelous condition ( by that I mean if its not all dirty) However, never , Never!, clean of the scratches with a wire brush that kills the value. Its worth from 30-50 $.
But if it has a tiny CC on the back you may need a magnifying glass, it could be worth from 50-500$
