Rarity & Collector Interest
While not rare, the 1990 Upper Deck Sosa card is popular among rookie card collectors and fans of '90s baseball memorabilia. The birthdate error is a minor production oversight and has been noted by enthusiasts, but does not reach the collectible error tier of more prominent print mistakes (e.g., reverse image cards or missing nameplates).
That said, this card captures an early phase of Sosa's career before his rise to stardom during the 1998 Home Run Chase, giving it added historical interest.
