The East Coast Collectibles Convention (EC3 Con) is New England’s premier destination for sports cards, Pokémon, TCG collectibles, memorabilia, and pop-culture fandom. Held quarterly at Mohegan Sun in Uncasville, Connecticut, EC3 Con brings together collectors, vendors, creators, and families for a high-energy, community-driven weekend of buying, selling, trading, and meeting special guests. Featuring 300+ vendor tables, live signings, on-site authentication, hobby podcasts, family activities, and one of the region’s most active Trade Nights, EC3 Con is built for collectors of all ages and experience levels. Whether you’re hunting for grails, showcasing your collection, discovering new artists, or exploring the hobby for the first time, there’s something here for everyone. EC3 Con is proudly produced by the same team behind East Coast Collectibles Card Shop in Middletown, CT, known for our customer-first approach and passion for growing an inclusive, exciting hobby community. Our goal is simple: create an unforgettable show experience where collectors feel welcomed, vendors thrive, and families can share in the excitement of the hobby together. Join us at our next EC3 Con and experience why thousands of collectors choose Mohegan Sun as their must-attend hobby weekend.
