Pete Rose Jersey..Please Help!

[sportsmoments]

Hello everyone. I am new to gameusedforum so please be patient. A gentleman who I have met through friends has presented me with a Game-Used Jersey of Pete Rose. He claims he purchase it from a major auction house in New York. The jersey comes with a LOA from Grey Flannel as well as letter from the original owners of the jersey stating how they obtained it. The LOA states that the jersey came from the mid 70's, however the exact year cannot be certain. The jersey has a red rawlings tag on the bottom of the jersey with the size 44 on it. Does anyone know what type of tags, markings, and or characteristics I should be looking for? I want the jersey, however I want to make sure everything is right on. Any help would be appreciated.
