Hello!  This is the 5 cent, 12 perforation, Deep Claret, #J-48 Postage Due stamp from 1910.  I'm not a grader but the front looks fantastic and is well centered (see pictures).  The back has at least some of its original gum and there is a hinge remnant.  The stamp will ship First Class in a protective sleeve and a plastic case.  It was stored in a smoke free home, at least from 1945 on.  Thanks for looking!
