Following the release of an expansion pack commemorating the 30th anniversary of the Pokémon Trading Card Game, people in their 30s and 40s have flocked to the used card market, leading to a surge in the number of listings and searches. Their purchases account for more than half of the total transaction value, with a particularly high proportion of high-value transactions. The experience of collecting Pokémon cards as children is analyzed as the main driver behind the resurgence of the collecting craze. Since the release of the expansion pack, trading activity has become even more active, and sellers who have been holding onto their collections for a long time are also participating in the market, with a wide range of transactions taking place, from small-value individual card sales to high-value collecting.
