To print this value two plates have been used, one prepared by Masini and the second one by De Masa, the stamps made with the second plate appeared from mid January 1859. Some details allow for the identification of the proper plate. Other minor details allow in addition for the identification of the group (right or left) from which the samples are coming. This last point, quite technical, will not be dealt here in detail: in the "Bibliography " section some suggested work is listed for the people who desires to continue the study To be noticed how in the1st plate the double, and multiple printings are quite frequent (some example can be found in the "Going Deep" section).
