East Coast Collectibles Convention

EC3 East Coast Collectibles Convention takes over the Mohegan Sun Expo Center in Uncasville for Father's Day weekend, running Saturday 10 AM to 6 PM and Sunday 10 AM to 4 PM. The convention floor will host 325 vendor tables, putting it firmly in the largest-show tier on the New England calendar, with buying, selling, and trading across sports cards, Pokémon, and TCG.

Saturday early bird admission opens at 9 AM for $30, and organizers note that early entry consistently sells out, so anyone planning to hit the floor first should grab tickets in advance. A Trade Night runs Saturday from 6:30 PM to 10 PM and is free to attend, giving collectors an after-hours window once the public show closes.

Two autograph guests are on the schedule: Demario "Pop" Douglas (autograph $50, photo-op $50, combo $80) and former New York Yankee Shane Spencer (autograph $20, photo-op $20, combo $35), with general admission required for both. Kids under 12 are free, and parking is always free.
