Helmeppo appears as card #010 in the One Piece Card Game Premium Booster (Japanese) as a Common Jolly Roger Foil variant. The description notes its place in early set runs and its relative ubiquity among commons, which contributes to a current market value of $0.00. Collectors tracking print frequency or set completion will treat it as a low-value but completing piece. Its foil Jolly Roger attribute may still interest set-focused builders and completers.
