The RetroMania Collectibles Show comes to the Boulder County Fairgrounds Exhibit Building in Longmont on Saturday, January 23, 2027, and the name tells you what makes it different. Most Front Range card shows are card shows with some collectibles at the edges. RetroMania inverts that — it is a nostalgia-driven collectibles event where trading cards share the floor with vintage toys, retro video games, comics, and pop-culture memorabilia. For collectors whose interests do not stop at cardboard, that mix is the whole appeal, and it draws a dealer base that does not otherwise circulate through the standard Denver-metro rotation.
On the card side, dealers cover MLB, NBA, NFL, NHL, UFC, boxing, and soccer with a natural tilt toward the vintage and junk-wax eras that fit the show's retro theme: 1950s and 1960s Topps and Bowman, 1970s and 1980s Topps, Fleer, and Donruss, and the 1990s insert and refractor product that a generation of collectors grew up on. Modern Panini Prizm, Donruss Optic, Select, Topps Chrome, and Bowman Draft is present too. Denver Broncos, Denver Nuggets, Colorado Avalanche, and Colorado Rockies material is available, and January puts the NFL playoffs at peak attention. Trading card game vendors bring Pokemon with unusual strength in vintage Wizards of the Coast material — Base Set, Jungle, Fossil, and Neo — alongside modern Scarlet and Violet and Japanese imports, plus Magic: The Gathering with genuine Old School and Reserved List presence, Yu-Gi-Oh!, One Piece, Disney Lorcana, and Dragon Ball Z. Locked cases hold PSA, BGS, SGC, and CGC graded slabs. Surrounding tables carry vintage action figures, Nintendo and Sega cartridges, comics, Funko Pops, arcade and pinball memorabilia, and hobby supplies.
Hours run 9:00 AM to 5:00 PM Mountain Time — a full eight-hour day with an early start. Admission pricing was not independently confirmed at the time of listing; check with the organizer before you go. VERIFY: admission price and children's policy not confirmed.
The Boulder County Fairgrounds Exhibit Building is in Longmont, accessible from Highway 119 and I-25 via Colorado 66, with extensive free on-site parking. The exhibit building is a single-level, heated, ADA-accessible hall with concessions. Longmont sits about forty minutes north of Denver and twenty from Boulder, drawing collectors from Boulder, Loveland, Fort Collins, Erie, and Broomfield who rarely make it to Aurora or Castle Rock shows.
The show suits nostalgia collectors above all — people who came for a 1987 Topps set and leave with a boxed Sega Genesis and a run of Amazing Spider-Man. Vintage card hunters do well here because the crossover crowd means card material is sometimes priced by dealers whose main focus is elsewhere. Families find it approachable and genuinely fun for kids. TCG players get access to vintage Pokemon and Magic inventory that metro shows have already picked through.
Practical advice: arrive at 9:00 AM, since crossover shows see the sharpest early buying. Bring cash, a want list covering all your categories, sleeves, top loaders, and a sturdy box or bag — retro purchases are bulkier than cards. Budget more time than you think you need.
