Two cards can share one set and number

One Piece, Digimon and a few other games print a parallel at the same number, and it can be worth a hundred times more.

In Pokémon a holo and a reverse holo are two printings of one card, and the Finish row answers which one you hold.

One Piece, Digimon, Gundam, Union Arena and Dragon Ball work differently. A parallel is a separate card with the same set and number.

Pick the one you hold

When a card has more than one version, the card panel shows a Version row with each one and its price.

Romance Dawn OP01-002 is Trafalgar Law at $2.12, and the parallel at the same number is $440.57. Nothing in a scan can tell them apart.

Pick your version and the price follows. A card with one version shows no row.
