Union Pacific spike driver from 1878

From: Tullcwbss@aol.com

Maybe you can help me. I have a Union Pacific spike driver from 1878; one side it says UPRR 78. It is in very good condition; handle has a split and is bowed. Also did they make reproductions of this spike driver? Any information you can give me would be a great help. Also can you tell if this has any value?
