(Runnemede,NJ) -- Rare Jackie Robinson artifacts are being auctioned ahead of the 75th anniversary of Robinson's major league baseball debut. A South Jersey auction house is offering several one-of-a-kind artifacts in a special catalog sale now through May 2nd. We're talking about the bat Robinson used during the 1949 all-star game and the plaque he received in 1962 when he became the first black player elected to the Baseball Hall of Fame. Number 42's 1951 Brooklyn Dodgers home jersey is also available. A 1950 jersey sold last year for more than four-million-dollars.
