I've been having some difficulty dating some 1990s Louisville Slugger TPX fielding gloves. The few I've seen or owned have had one star on the back, four stars, and five stars on the back. I've heard that these stars have to do with when these gloves were made - and thus used. Does anyone have some more information? Below are more thorough descriptions of some of the features of these gloves.

On the one-star glove, the pocket reads "TPX Tournament Players Series" and to the right, "Horween USA Leather." One five-star glove reads "TPX Pro" in the pocket, with a circle around it. The right side says, "Genuine Steerhide Leather." Another five-star glove reads "TPX Tournament Players Series" in the pocket and "Horween USA Leather" on the right side. Finally, a four-star glove reads "TPX Pro" in the pocket and "Horween USA Leather" on the right side.

If anyone can give me help with this, I'd greatly appreciate it. I'd really like to date these gloves and figure out when they were used.
