An error card is a sports card with a mistake in the design, text, image, or production process. Some errors are collectible, but not every mistake adds value.

The Sports Card Portal glossary is a collector-focused guide to the words, phrases, product terms, and buying language used across the hobby. It is built for people reading release calendars, joining group breaks, researching checklists, shopping for singles, comparing grades, or trying to understand why a certain card is considered a hit.
Each term has its own friendly URL so collectors can link directly to explanations for rookie cards, refractors, case hits, parallels, redemptions, autographs, relics, grading, retail boxes, hobby boxes, and other common card language. The starter list is based on public hobby term names, while the definitions and articles are generated as original Sports Card Portal content.

Event-worn means a card contains material worn by a player during a team or league event, such as a draft, combine, photo shoot, or promotional appearance. It usually signals limited-use memorabilia, but it is not the same as game-worn.
