About Us


Circle Auction is based in Kansas City with roots in the trusted Brown Button Estate Sales name. 

For the uninitiated, auctions can seem both confusing and intimidating. We want to change that. Circle Auction was created to make the process of buying and selling exceptional objects at auction easy, intuitive, and enjoyable. Auctions are such an incredible service for buying and selling unique, noteworthy, one-of-a-kind, interesting, significant items. We want to introduce this world to a whole new group of buyers and sellers; making the buying process simple and enjoyable, while making the selling process easy and profitable.

Circle Auctions’ curator is Charles Keller. As a formally trained ISA appraiser, Charles brings over two decades of auction industry experience and leads our specialists with a remarkable depth of knowledge. He has handled everything from ancient Egyptian antiquities to 1936 Olympic Gold Medals to 21st century militaria, and consulted with such institutions as the Van Gogh Museum in Holland, Imperial War Museum in London, New York Times, BBC, and locally at the National World War I Museum in Kansas City.  

For every seller whose items we bring to auction and every buyer we connect to a new and exciting object, we’re here to make the process easy, intuitive, and thoroughly enjoyable. Circle Auction hosts category-specific auctions once a month, specializing in art, jewelry, antiques, fashion, and modern design. 

Circle Auctions is a member of the National Auctioneers Association, Missouri Auctioneers Association, and Kansas Auctioneers Association.
