Near Mint condition, current market prices. Includes every card in the set: base printings, reverse holos, and secret rares.

Undone Seal is an ADV-era set from January 2004 that represents a transitional period in Pokemon TCG history, featuring the introduction of ex mechanics that would define competitive play for years to come. The set contains 83 cards with a strong focus on Metal-type Pokemon, including powerful ex variants like Registeel ex and Metagross ex that command premium prices. Collectors should note the unusual pricing anomalies in this set, particularly commons like Vulpix and Oddish trading at inflated prices, which may indicate scarcity or niche demand rather than broad market strength.

Investment Outlook Neutral While key ex cards maintain solid value, the pricing instability and age of the set suggest limited growth potential without sustained collector interest in ADV-era nostalgia.

Reprint Risk Medium The ex mechanics and popular Pokemon in this set are periodically revisited through modern products, creating moderate reprint risk for non-ex holos.
