Clean Auto
An autograph that is bold, legible, and well-placed on the item.
A "clean auto" refers to a signature that is visually appealing — bold ink, clear letter formation, and well-centered placement on the item. Clean autos command premiums over sloppy or poorly placed signatures.
For trading cards, a clean auto means the signature doesn't bleed into the card design, is centered in the designated signing area, and uses consistent ink. BGS (Beckett Grading Services) actually grades the autograph quality on a 1-10 scale.
Collectors pay 10-30% premiums for exceptionally clean autos, especially on high-value rookie cards where the signature quality can significantly affect the overall grade and desirability.
