Card Show Weekend Preview June 20-21: Collect-A-Con Las Vegas, EC3CON, and More
The June 20-21 weekend is stacked, led by Collect-A-Con at the Las Vegas Convention Center and EC3CON at Mohegan Sun. Here is the rundown of headliners, regional shows, and how to work a busy show floor.
The next big show weekend is almost here. Looking ahead to June 20-21, 2026, collectors have a stacked slate of card shows and conventions to choose from, headlined by a major Collect-A-Con stop and a New England staple. Here is what is worth planning around.
The headliners
Collect-A-Con Las Vegas takes over the Las Vegas Convention Center with what bills itself as the nation's largest trading card, anime, and pop-culture convention. Expect 500-plus dealers, box breaks, celebrity guests, live concerts, and tables covering sports cards, Pokemon, video games, comics, and vintage toys all under one roof.
On the East Coast, EC3CON (East Coast Collectibles Convention) returns to Mohegan Sun in Uncasville, Connecticut. New England's premier card destination runs 330-plus vendor tables spanning sports cards, Pokemon, TCG, memorabilia, and pop-culture fandom, with special guests on hand.
Regional shows worth a drive
- Milwaukee, WI — a 125-plus table show serving Wisconsin, Illinois, and Minnesota collectors.
- Albany, NY; Ashburn, VA; Tempe, AZ; Cooper City, FL; Shelby, NC; Corbin, KY — regional events round out the weekend across the country.
How to work a show weekend
A few habits make any show more productive. Set a budget before you walk in, and bring cash — many dealers price better for it. If you are buying graded cards, inspect slabs in good light and bring a loupe. Hunting raw cards to grade? With grading turnaround times stretched right now, be selective about what is actually worth submitting. And if you are selling, know your comps before you negotiate so you can move quickly when a fair offer appears.
Two flagship conventions, a strong Midwest show, and regional events coast to coast — June 20-21 is a weekend worth circling.
