Sunday, November 1, 2026 closes the three-day All American Collectors Expo at the Douglas County Fairgrounds in Castle Rock. It is also the day daylight saving time typically ends, which means an extra hour of sleep and, more practically, a room full of dealers who are well rested and facing the last session before a long drive home. The final day of a multi-day expo consistently produces the weekend's most flexible pricing, and this one sits squarely in that pattern.
The floor holds up well on the closing day, with dealers reorganizing cases overnight and often surfacing material they held back earlier. Sports card dealers cover MLB, NBA, NFL, NHL, UFC, boxing, and soccer across all eras: vintage 1950s and 1960s Topps and Bowman, 1970s and 1980s Topps, Fleer, and Donruss, 1990s insert and refractor product, and modern Panini Prizm, National Treasures, Donruss Optic, Select, Mosaic, Topps Chrome, and Bowman Draft. Denver Broncos inventory is at peak interest with the NFL season at its midpoint, and Denver Nuggets and Colorado Avalanche material draws steady attention with both seasons a few weeks old. Colorado Rockies collectors get an offseason market that is quieter and, for patient buyers, cheaper. Trading card game vendors carry Pokemon spanning vintage Wizards of the Coast through Scarlet and Violet and Japanese-language sets, plus Magic: The Gathering, Yu-Gi-Oh!, One Piece, Disney Lorcana, Digimon, and Dragon Ball Z. Locked cases hold PSA, BGS, SGC, and CGC graded slabs, and additional tables carry autographed memorabilia, comics, Funko Pops, retro toys and video games, coins, and hobby supplies.
Sunday hours run 9:00 AM to 4:00 PM Mountain Time — a seven-hour day, one hour shorter than Saturday, so the closing window arrives sooner than you might expect. Admission pricing was not independently confirmed at the time of listing. VERIFY: admission price, three-day pass availability, and children's policy not confirmed.
The Douglas County Fairgrounds sits in Castle Rock with straightforward access from I-25 roughly midway between Denver and Colorado Springs, offering extensive free on-site parking. The exhibit buildings are single-level, ADA-accessible, and heated, with on-site concessions. Early November along the Front Range can bring the first real cold snap, so dress for the walk in from the lot.
Sunday belongs to negotiators and sellers. Dealers closing a three-day run would far rather convert inventory to cash than reload the trailer, and offers refused on Friday or Saturday frequently land by early afternoon. If you are selling a collection, dealers who did well over the weekend arrive Sunday with cash and case space. Set builders find dealers willing to break lots. Families and newcomers get a calmer floor and dealers with the patience to explain grading and pricing properly.
Play it tactically: arrive by 9:00 AM to revisit anything you flagged, and lead with a specific number rather than asking what something costs. The 2:00 PM to 4:00 PM stretch produces the weekend's best deals. Bring cash, a want list with target prices, penny sleeves, top loaders, and a box. Confirm final-day hours with the organizer before you go.
