I was wondering if anyone knows of any US based companies that authenticate soccer shirts from the various major European Leagues (Serie A, Ligue I, La Liga, Bundesliga, EPL) or the minor Americas Leagues (LigaMX, MLS) for match use. I found a company in Italy that does it, but they have a really, *REALLY* weird way of wording their certificates by saying they are "Race" Worn or Ready.

I'm hoping to find someone that can actually authenticate use in a match. I tried photo-matching as an alternative, but many shirts are generally non-descript (solid colors), which makes photo-matching based upon patch positioning a bit more difficult. That is, when I can even find footage of the matches.

This would be for contemporary (post-2017) shirts, so it really shouldn't be this hard to do. I chalk it up to personal incompetence.
