To print this value three plates have been used, the first two prepared by Masini and the third one by De Masa; the stamps made with the second plate appeared from mid February 1858 and the one of the third plate from mid December of the same year. 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.

Fig. 3: 3rd plate

1st PLATE (Fig. 1)
In the lower margin a horizontal color line is visible, while in the upper margin either is not visible or is visible partially or quite dimly.
The printing itself is often pale, tending towards pink and not so visible.
2nd PLATE (Fig. 2)
In the upper margin is often visible a color line, enough far away from the stamp frame; the lower margin is white.
The vertical space between two stamps is 6 mm instead 4 mm like in the other two plates.
Under the first "N" of "NAPOLETANA" is visible a small white sign (in some samples is not visible)
The label "G: 2" is often smeared giving the impression to be stretched; the distance between the label and the horizontal line just under it is less than in the other plates and sometimes the label and the line touch each other.
Th right margin is often colored.
3rd PLATE (Fig. 3 )
In the upper margin a color line more or less evident and shaded is visible, while it is not present in the lower one, that is completely white.
The line is closer to the stamp margin in comparison with the 2nd plate (Note: in this particular sample, to say the truth, the line in evidence is the composition line, that is visible in same values; the one between stamp and stamp is anyway quite similar, only less sharp and thin).
The left margin presents often a colored line very evident.
The colors are brighter than in the other plates, tending toward the carmine; the printing is a bit heavier and the details more visible in comparison with the other two plates.
