Same card, different version

A parallel is a variant of a base card — a different color, a foil or refractor finish, or a serial-numbered version. The image is the same, but the version is not, and the rarer the parallel, the more it is worth.

Numbering signals scarcity

Many parallels are serial-numbered (for example /99 or /10), and a one-of-one is the single rarest copy. Lower print runs mean higher scarcity and, usually, higher prices.

Identify before you value

Confusing a base card with a rare parallel is a costly mistake. Pin down the exact parallel and grade, then value it from real comps — which is exactly what Slabline does per card.
