Kevin, is there a seam line? It and the lack of the cent sign mean that it is Scott 2226. This stamp was printed on the "B-press" and the design was slightly modified so the plates would fit this press. Plates 2, 4, 8 & 10 were printed on the old, now dismantled Cottrell presses and show a distinct seam- or joint line. Go to
