Counter Attack! #ST-54 belongs to the Digimon Trading Card Game, appearing in the Series 1 Starter set as an Unknown rarity piece. Collectors can view it as a starter-era card with limited rarity information, which makes provenance and condition more important when assessing value. Current market listings show a value of $0.00, suggesting no recent confirmed sales or market demand. Its presence in early starter product lines gives it niche interest to set completists and archival collectors.
