This auction features a PSA9 set of iconic cards from the Team Rocket expansion of the Pokémon Trading Card Game, released during the late 1990s—a period that saw the franchise's explosive popularity following the anime's debut in Japan in 1997.

The ex cards, especially those of Mewtwo and Moltres, are highly sought after due to their limited print runs and the nostalgia they evoke among collectors who remember the original series.

The pristine condition of these cards, with the Mewtwo ex being stored immediately after unsealing, elevates their collectability, as even slight imperfections can significantly affect value.

Given the historical importance of the Team Rocket series and its rarity, this listing sits competitively within the current Japan-market landscape for early-run collectibles.
