The single owner collection focuses on some of the hobby's most sought-after names, including Mickey Mantle, Babe Ruth, Lou Gehrig and Hank Aaron. Highlights include two 1933 Goudey Babe Ruth cards, a 1952 Bowman Mickey Mantle and a 1954 Topps Hank Aaron, with every card third-party graded by PSA or SGC. Built through years of collecting with family and searching shows, auctions and dealers across North America, bidding will close on September 27, 2026, with all lots offered in Canadian dollars.
