About: Error card

In the trading card collecting hobby, an error card is a card that shows incorrect information or some other unintended flaw. It can contain a mistake, such as a misspelling or a photo of someone other than the athlete named on the card. Depending on whether the manufacturer noticed the problem while the cards were still being produced, a card may exist in both correct and incorrect versions. If the correction is made sufficiently early in the print run, the error card may be significantly rarer and more valuable than the corrected version. However, the opposite may be true if the error is corrected late in the printing cycle, resulting in a smaller population of the corrected version of the card compared to the error version.
