Definition: An error card is a sports card that contains some sort of mistake, such as a misspelling or a photo of someone other than the Cub player named on the card. In previous decades, card manufacturers often corrected errors when they were discovered. This led to situations where one of the cards - either the correct or incorrect version, depending on when the mistake was found and how many of each type got into circulation - sold for substantial premiums on the secondary market.
abbreviated terms or acronyms:
UER-means Uncorrected Error so no more cards with the right info where every made
COR-means Corrected Error so there are different variations

1956 Topps team the Cubs The different cards are commonly referred to by collectors as the "dated", "undated" and "centered" cards. The first release showed a team picture, obviously taken the year before and correctly labeled as "1955 Chicago Cubs. For some reason, perhaps because it was confusing to have a card labeled "1955" in a 1956 set, Topps reprinted these cards, blacking out the space where the date had appeared. This resulted in the team name being off center in the black box where it appeared. Topps finally issued a third version with the team name centered in the box.
