Tuesday, October 20, 2026 marks the third October running of the Wolfpack Collectibles TCG Card Show at Diamond 9 Sports in Placentia. With the Minted Collectors Cup in Fullerton and the Halloween weekend shows just ahead, this is the night many north Orange County collectors use to fill holes in their binders and to sell what they want to turn into cash before the end-of-month events.
The lineup of vendors changes every week, but the categories are consistent. Pokemon is the anchor: current-set singles and chase cards, vintage WOTC holos, Japanese exclusives, sealed product and graded slabs. One Piece, Magic: The Gathering, Yu-Gi-Oh!, Disney Lorcana, Dragon Ball Super and Union Arena are all represented by at least one dedicated seller most Tuesdays, and some vendors bring non-TCG items like Funko Pops or anime figures on the side. Diamond 9 Sports also opens its sports card case, so you can browse MLB, NBA, NFL and NHL cards while you are there.
The show runs 3:00 PM to 9:00 PM. Admission is free and no tickets are needed. Vendor tables are 30 dollars and are reserved in advance at d9sportscards.com; the low cost makes this a popular place for collectors to sell down duplicates without committing to a full weekend show.
The venue address is 1850 N Placentia Ave, Placentia, CA 92870. It is easiest to reach from the 57 Freeway at Yorba Linda Boulevard, and there is free parking in the shopping center lot right in front. Collectors coming from Santa Ana should budget 20 to 30 minutes on the 55 and 57 freeways.
Who it is for: Pokemon and One Piece players preparing for weekend tournaments, families with young collectors who want a safe and free first event, casual traders who like a small weekly show with familiar faces, and anyone thinking about vending for the first time. It is not a large sports card show, but the shop case is a nice bonus for crossover collectors.
Tips: late October is a strong buying night because sellers are clearing inventory ahead of holiday releases; make reasonable offers on bundles and bulk lots. Bring cards to trade, a want list, cash in small bills, and sleeves or toploaders for raw purchases. If you plan to play, bring a sleeved deck for pickup games after 6 PM. Ask the Diamond 9 counter about grading submission deadlines if you want slabs back before the holidays. Follow the Wolfpack Collectibles Instagram the day of the show for vendor previews and any giveaway announcements. One more practical note: the room is small enough that you can see every table in a single lap, so do the lap first, note prices, and then go back to buy; the same card is often at two or three tables and the spread can be significant on a Tuesday night when sellers are pricing by feel rather than by a live market check.
