I have been in the business since 1959 and have gotten almost everyone possible in person in all sports from Ali Mantle.
In 1984 I started the first sports auction ever called Sports Auctions of New York.
I have bought and sold Rocky Marciano's Golden Gloves Belt and shorts, Lou Gehrig's game used uniform and 1932,933 contract, Josh Gibsons players contract, James Naismith letter, Bill Walton, Karl Malone game used jerseys, Gordie Howe and Wayne Gretzky game used uniforms. You name if I can't find or haven't sold it then it is almost impossible to find.
If you are a true collector then you know my company Les Wolff Sports LLC. I have been Sports Collectors Digest since the early 1960's.
I am a certified Appraiser with the International Society of Appraisers.
I traveled the country for ESPN in 2005-06 telling people what there items are worth. If you are looking to have an item appraised, auctioned, appraised just contact me.
Remember I am a full time collector and dealer.
