🏆 About
Established in 2003 by Stan House and Roger Rumsey, 4 Sharp Corners is the world’s largest seller of PSA-graded sports cards. Over the course of the last 20 years, we have submitted more cards to PSA (over 3.5 million and counting!) than any other company in history and we continue to offer the largest variety and inventory of graded sports cards available anywhere. From pre-war to modern, baseball player sets to Star Wars and Pokémon, we have assisted hobbyists in building their collections and completing their PSA Set Registries. As lifelong collectors ourselves, we understand the diversity of the collecting community and the “thrill of the hunt” for finding the most elusive pieces of a set or project. We will always work to deliver great cards and service to fellow collectors. Note ONLINE ONLY.
💬 Collector Notes
Independent editorial assessment
This shop is a “Grade-A” TCG destination. It’s clean, well-lit, and the staff knows their “comps” inside and out. Pro Tip: They are a major hub for Pokémon trade nights; if you have rare slabs to move, this is the most liquid market in the area.
