To many factors to define here:
How old is it?
What condition is it in?
Is it used or mint?
Exactly what stamp is it?
Consult a stamp catalog at your local library. The introduction will explain about grading stamps. The catalog will help you identify the specific stamp and what its catalog value is. Most dealers will pay 10 to 20% of the catalog value for a stamp with some value to it, perhaps even more if it is really high value. Most of the stamps in that time frame from the US are going to be of minimal value, but there are some nice exceptions!
