A signed sports jersey is a piece of athletic clothing, typically a shirt, that has been autographed by a player or a team. These jerseys are often collected by fans as memorabilia, representing a connection to their favorite athletes or teams. The signature can add significant value, especially if the player is well-known or has achieved notable accomplishments. Collectors often seek out signed jerseys for display or investment purposes. Authenticity is crucial, so many jerseys come with certificates of authenticity or are accompanied by photographs of the signing event. Popular sports for signed jerseys include football, basketball, and baseball.
