Parallels are alternate versions of a base card with a different look — usually a colored border, foil treatment, or refractor finish — often produced in smaller quantities than the base. Many sets have a whole "rainbow" of parallels, from common ones to rare numbered versions (like /99, /25, or a one-of-one). Because they're scarcer and flashier, parallels typically carry premiums over the base card, and the rarest can be a set's most valuable chase cards. Collectors sometimes chase the full rainbow of a favorite player. When buying, check the exact parallel and print run, since value can vary enormously between two cards that look similar. Your local shop can help you identify parallels.
