The largest collection of Pokémon memorabilia is 17,127 items, achieved by Lisa Courtney (UK) in Welwyn Garden City, UK, as verified on 10 August 2016.

Her collection includes items from the UK, USA, France, and of course, Japan. She has made several trips to Japan for the specific purpose of collecting Pokémon merchandise, each time sending between 8-12 boxes full back to the UK. Some items from her collection (as well as her Guinness World Records certificate) have been displayed at the Museum of Hertford as part of an exhibition on popular culture.

Asked what’s still on her wishlist, she told us: “I’m still searching for the Pokémon Center deluxe-size Tyranitar plush. I’ve been looking for him for over 10 years.”
