Autograph Card
Also known as: Auto, AU, Certified Auto
An autograph card (or "auto") is a trading card that features the signature of the player, athlete, or subject depicted on the card. Autographs are certified and inserted directly by the card manufacturer, giving them significantly more value and authenticity than cards signed outside of the factory. Certified autos are typically sticker autographs (a signed sticker applied to the card) or on-card autographs (signed directly on the card's surface — preferred by collectors). Autograph cards are among the most valuable cards in any product.
