This was a game ball in the 1968 Rose Bowl game between Indiana University and USC with OJ Simpson being a popularly named star of the game. Simpson was also the Heisman Trophy winner that SE year.
Thank you for submitting your item for appraisal. This appears to be a vintage R5 Rawlings Intercollegiate Football in played with condition with the provenance you described. Anything OJ Simpson related will be rather neglected by collectors. Recent auction results for such memorabilia were very very modest. The estimate is based on these auction results.
