An early Digimon TCG piece from the 1999 Upper Deck Exclusive Preview set, 10 Biyomon is cataloged as card #13 with an Unknown rarity. Collectors view it as a niche preview-era item rather than a competitive play piece, and current market listings show a value of $0.00. When grading or provenance data appear, prices can shift, but the card generally holds interest for historical or completionist collectors.
