East Coast Collectibles Convention – Mohegan Sun, CT — Mar 27, 2027

East Coast Collectibles Convention, usually shortened to EC3CON, is a quarterly Pokémon, sports card and collectibles show held in the Earth EXPO Center at Mohegan Sun in Uncasville, Connecticut. It runs more than 350 vendor tables and draws collectors from across New England and the Northeast. The show suits families as much as dealers, and the organizer also runs a card shop in Middletown.

What you'll find on the floor

Pokémon and sports cards lead the floor, with non-sports cards and general collectibles filling out the aisles. More than 350 vendor tables are on hand, with dealers coming in from across the country. Special guests are part of the lineup, mostly voice actors from anime and Pokémon: Tyler Bunch, Ted Lewis, John Swasey and Matthew Sussman, plus Boston Red Sox player Mickey Gasper. Guest appearances can change, so treat any name as likely rather than certain.

Authentication and grading are covered on site. JSA provides authentication both days of the show, and SMR Collectibles attends as an official mail-in partner for PSA and Beckett grading, though not as an on-site grader. TGA also offers grading at the show.

Dates and format

Most editions are a single day, while the holiday and Father's Day weekends run two. Hours for the November show are an early bird entry at 9 AM on Saturday only, general entry from 10 AM to 6 PM on Saturday and 10 AM to 4 PM on Sunday. Kids under 12 are free with an adult. Tickets can be bought online ahead of time or at the door, and all sales are final and non-refundable unless an event is canceled or rescheduled.

Trade Night

Two-day weekends include a Trade Night after the first day. It is free and open to the public, with no ticket required, so collectors who skip the main floor can still swap with each other in the evening.

Vendor tables and rules

Tables are currently sold out for the upcoming show, and a waitlist is open. The list carries over from past shows, so a vendor who signed up within the last two years does not need to sign up again.

A standard table is one 8-foot table, two chairs and a tablecloth. Each vendor gets two badges with the first table and one more per additional table; extra badges are $50 each at check-in. Load-in begins at 5:30 AM on Saturday, and vendors must be fully set up by 8:45 AM.

Getting a table is a two-step process. Joining the waitlist or being invited to apply does not reserve space. A vendor application has to be approved and payment processed in full before a table is confirmed. If a payment fails after approval, the vendor has two business days to fix it before the table is released to someone else. Invitations from the waitlist are first come, first served, and communication with the organizer is expected to stay respectful and professional.

Getting there

The Earth EXPO Center is at 1 Mohegan Sun Blvd in Uncasville, Connecticut. Parking is free everywhere at Mohegan Sun, and the winter parking garage or its adjoining lot is closest to the event. Dining, including concessions, is within walking distance of the Expo Center, and the building is stroller friendly. Out-of-town visitors can book through a hotel room block at the Hyatt Place Uncasville / Casino Area, 2049 Norwich New London Tpke, under the group name The East Coast Collectibles Convention, group code G-CCE3.

The organizer's card shop

East Coast Collectibles also runs a card shop at 386 Main Street in Middletown, Connecticut, inside The Main Street Market. It stocks more than 10,000 singles, sealed sports and Pokémon product, and secure glass cases for premium items, plus a ripping area stocked with free penny sleeves and top loaders. Monthly free events include Trade Night and Lego Night.

Who it suits

EC3CON fits Pokémon and sports collectors who want a large floor with many dealers in one room, families who can bring kids under 12 free, and anyone who wants grading or authentication help without leaving the building. Vendors should plan ahead, since tables sell out and the waitlist is the way in.
