💬 Collector Notes
Independent editorial assessment
This shop is a primary source for “wax” (sealed product) collectors. They carry everything from vintage 1980s factory sets to high-end current releases like National Treasures and Bowman Chrome. Consumer Tip for 2026: Because Diamond Cards operates a very high-volume online business, their pre-order system is highly competitive; some users have reported order cancellations if the shop is “oversold” on hot releases like Mosaic Basketball. However, they are consistently praised for having some of the lowest prices found online for hobby supplies and packs. If you visit in person, be sure to ask Shawn about Flash Sales, which they frequently run to move older inventory and sets.

⭐ Review Summary
Diamond Cards in Quincy, Illinois, is a landmark destination for collectors, holding the title of the oldest sports card and memorabilia business in the tri-state area (Illinois, Iowa, and Missouri). Founded in 1988 by Richard “Dick” and Barb Chapin, the shop is currently owned by Barb and managed by Shawn Hasting, who joined in 2008. The shop is highly regarded for its massive inventory of sealed hobby boxes and cases across all major sports (Baseball, Football, Basketball, Soccer, and UFC), and it has a significant national presence through a robust online storefront. While it maintains an “old-school” feel in its physical location, Diamond Cards is known for its modern expertise, fast shipping, and a deep selection of Pokémon TCG.
