Elvis Presley can still lick them all when it comes to his post office popularity - the late rocker's stamp remains the US Postal Service's most-collected stamp. Americans have saved 124.1 million stamps from the 1993 Elvis Presley release - almost 40 million more than a collection called the Wonders of America, which comes in second. A 1993 collection of stamps featuring musical pioneers like BILL HALEY, Otis Redding and Buddy Holly is also a philaterer's favourite in America - it comes in fourth on the new US Postal Service list, just behind a collection of wildflower stamps.
