It is most likely a jersey from a Cuban sugar mill team, which was the Cuban equivalent of the many local semi-pro teams in U.S. during the same time period. It definitely has some value, but only a fraction of a professional team jersey. Again, probably the same monetary difference of an American semi-pro jersey compared to a Major League jersey.
If you are looking to sell, there is a MAJOR collector of Cuban jerseys in Florida that has a museum-quality collection and would probably be your best bet for a prospective buyer. I might be able to put you in touch with him if you e-mail me privately.
Good luck,
-Ryan
