We are more than just a business—we are a community of dedicated collectors committed to providing the best inventory and service in the hobby. Since 2003, our mission has been to elevate the collecting experience for every enthusiast, from seasoned investors to new hobbyists.

Our History: From Passion to Industry Leader

Established by lifelong collectors and childhood friends Stan House and Roger Rumsey, 4 Sharp Corners was founded on a shared passion for the "thrill of the hunt." What started as a personal collection journey has evolved into being one of the world's largest sellers.

We have a deep understanding of the market and the diverse needs of the collecting community.
