Autographs & memorabilia
Autograph
Also called: auto, on-card auto, sticker auto
An autograph card carries a player's signature, either signed directly on the card (on-card) or on a clear sticker applied to it (sticker auto). On-card autos are generally preferred.
An "auto" is a card with a real signature. There are two main kinds: an on-card autograph is signed directly onto the card surface, while a sticker autograph is signed on a clear label that the manufacturer then places on the card. Collectors usually value on-card signatures more because they look cleaner and feel more authentic.
Autographs are often combined with memorabilia, as in a rookie patch auto, and most are serial numbered.
Why it matters: signed cards are among the most valuable in any product, and whether an auto is on-card or sticker, plus the print run, can meaningfully change its price.
