Is there any extra value to stamps that have been signed by their originator?
Yes these stamps will have a premium added to the normal stamp value due to the fact they were autographed by the man to produced the bill to get the stamp issued. That said, They would be sough out by specialists for example, a specialist in the stamp, a firefighting topical collector, a firetruck topical collector etc. Connecting the stamp with the interested collector is the hard part.
J. Caleb Boggs, who I believe sponsored a bill....
Feel free to say it this way next time, "J. Caleb Boggs, who sponsored a bill...."
