What collectors say
★★★★★
“These guys are great for grading! Did a test with submissions to PSA. Sent all these early December 2025. Status on this day. Jan 31, 2026 1. Courtside Collectables - 4 cards received back Jan 31, 2026 2. Myself - 4 cards just went to research and ID, not even grading yet. 3. Game Stop - 4 cards Status PSA received. Not even grading yet. Seriously if you want your cards graded quicker than doing it yourself or with Game Stop, I would go with Courtside Collectibles. Honestly, it was cheaper and saved me time with packaging and shipping them myself. I've used Courtside in the past and was bummed they stopped for a year cause people were crying about how long it took. SO HAPPY THIS SERVICE IS BACK. Don't be an A-hole, half of you don't even know how quick this service is from Courtside! You should be thankful it's available.”

“Highly recommend this family owned card shop! Good prices, nice selection, and friendly/knowledgeable employees. They spent a good bit of time answering my questions about grading cards and the hobby in general. I spoke with Emma & Nick for a while and gained a lot of good information from them. They have all sorts of cards (Pokemon, Magic, Sports, etc.) in singles & boxes, as well as supplies. They also do breaks on Youtube & Whatnot. This will be my go to card shop from now on!!”
★★★★
“Great people with a wide selection of cards and fairly priced singles. You will definitely pay more for ETBs because they go through third-party sellers, which increases the cost. Of course, the store also needs to make money, so they mark them up a bit to turn a profit.””
★★★
“Very nice people they just dont offer much when they buy your graded psa slabs only got 70% wish I would have waited to look around before selling my psa slabs”
