A voucher signed by Shoeless Joe Jackson (1887-1951) is among the top lots at Heritage Auctions' July 30-31 sports memorabilia sale.

The lot is expected to make in excess of $100,000.

Shoeless Joe Jackson played for the Chicago White Sox

Jackson's autograph is among the rarest in the hobby, due largely to his illiteracy. This cheque for $500 made out to the Savannah Realty Investment Corporation is one of very few autographs he ever signed.

Heritage explains: "Even the most casual collector of sports memorabilia is aware that Jackson's autograph stands as one of the hobby's 'Holy Grails,' the vast gulf between supply and demand fueled by the legendary slugger's illiteracy and his supreme baseball relevance respectively.

"Typically Jackson would avoid signing autographs whenever possible, allowing his wife to tend to those duties when possible, and only assuming them himself when legal matters demanded.

"Here we encounter just such an instance, providing one enterprising hobbyist the opportunity to elevate his collection to a level that few others could match."

Another Shoeless Jackson signature made $42,000 at Heritage last year.
