Sun Seed [Cosmos Holo] appears in the Pokémon TCG Classic: Venusaur Deck as card #27 with an Unknown rarity classification. The entry is part of a themed deck release rather than a numbered expansion, so collectors often view it as a niche playtest or promo-style piece within Venusaur-focused sets. Current market listings show a value of $0.00, indicating negligible demand or lack of recent sales data.
