The September 22, 2026 Wolfpack Collectibles TCG Card Show is the third Tuesday-night edition of the month at Diamond 9 Sports in Placentia, and by late September the tables are usually stocked with product from the fall Pokemon set release, which tends to make this one of the busier evenings of the season for singles hunters.
Expect a trading card game marketplace rather than a general collectibles show. Pokemon is the main event: current-set chase cards, special illustration rares, vintage holos, Japanese exclusives and graded slabs from PSA, CGC and Beckett. One Piece, Magic: The Gathering, Yu-Gi-Oh!, Disney Lorcana, Dragon Ball Super and a few Union Arena and Riftbound sellers round out the tables. Sealed product is usually available in the form of booster boxes, elite trainer boxes and Japanese boxes, and Diamond 9 Sports keeps its own sports card case open for MLB, NBA and NFL collectors who tag along.
The show runs from 3:00 PM to 9:00 PM on Tuesday, September 22. Admission is free. Anyone can vend for 30 dollars a table, booked in advance at d9sportscards.com, which keeps the seller mix fresh from week to week.
Diamond 9 Sports is located at 1850 N Placentia Ave, Placentia, CA 92870. Take the 57 Freeway to Yorba Linda Boulevard and head east; the shop is in the center on the south side of the intersection with free parking out front. From central Santa Ana, plan on 20 to 30 minutes depending on traffic on the 55 and 57.
Who it suits: competitive Pokemon and One Piece players stocking a deck, parents looking for a safe first card show for their kids, and binder traders who prefer weeknight events where the pace is slower and deals are done face to face. If you mostly collect sports cards, treat this as a quick stop rather than a destination.
Tips: bring cards to trade, because the strongest deals at Wolfpack are swaps rather than cash purchases. Have a rough idea of market prices from TCGplayer before you go, but be open to trading up rather than nickel-and-diming. Small bills matter for the dollar-bin tables. Bring your own sleeves and a deck box if you plan to play casual games at the open tables; there is usually a pickup game or two of One Piece or Pokemon going on after 6 PM. A few regulars also run informal grading checks, so if you are on the fence about submitting a card to PSA, bring it along and ask for a second opinion on centering and surface before you pay a grading fee. Late September is also when many sellers start clearing summer inventory to make room for holiday product, so watch for bundle deals on older sets and bulk lots that can be worth far more than the sticker price once sorted.
