Beldum δ

Beldum δ is a Metal/Psychic dual-type Pokémon card from the 2005 Delta Species set, notable for introducing the unique δ (Delta) mechanic that gave Pokémon unusual secondary types. The Delta Species set has moderate collector appeal as part of the ex-era vintage, though common cards from this set typically remain in bulk territory. Current pricing data is unavailable, suggesting minimal market activity and stable low-end valuations typical of common cards from this era.
