I think you may have included a bad year (1982). He was a member of the Packers from 1956-1971. If it truly is a 1982 ball, he may have signed it at "Bart Starr" day, but if it's not an actual game ball from his era, the value will be lower. Bart Starr was the coach that year.
Bryan Bartlett "Bart" Starr was born on the 09 January 1934 and was a professional American football player and coach. He played as a quarterback for the Green Bay Packers and was name MVP in the NFL twice.
