The 2024 National Sports Collectors Convention in Cleveland has demonstrated a robust and sustained interest in sports cards and collectibles, four years after a pandemic-induced resurgence. The event attracted unprecedented crowds, with attendees reporting that the convention space had never been so packed since its last occurrence in 2018. Originally a small community, the collector base has expanded significantly through social media, connecting individuals during lockdowns and maintaining their enthusiasm post-pandemic. Attendees spent long hours trading cards, with at least one on-site trade night being shut down due to overcrowding. Notably, the convention also engaged a younger demographic, with a vibrant kids-only trade zone bustling with activity. This diverse participation suggests a promising future for the hobby as it evolves beyond nostalgia into a multi-generational interest.
