This Lillie Extra Battle Day card, graded PSA10, represents one of the most coveted Japan-exclusive promotional releases within the Pokémon Trading Card Game’s limited print runs.

As a character from Sun & Moon’s popular Alola arc, Lillie’s merchandise commands steady collector interest due to her narrative significance and the scarcity of promotional variants like Extra Battle Day.

PSA10 cards from this period—produced amid the franchise’s late 2010s boom—are rarely offered in pristine condition, especially direct from Japan, ensuring authenticity and optimal preservation.

The ¥600,000 price point reflects typical high-end valuations for museum-grade cards in the domestic market where grading standards remain stringent.
