History of the Postage Stamps of the United States of America

With an extra line on both sides, f^{1 2} g³ f⁴ k¹ k².

With an extra line outside the left frame line, but far from it (almost the same distance as the frame line is from the blocks), f¹ f² h³ g⁴ l¹.

With the frame line thin, often broken, and the extra line heavy and further off. The outer line is really the one drawn on the plate, and the inner line probably put in afterwards. A number of differing specimens. Also one in which there is no side line on the left except a very thin line from the level of the chin down, and another from the middle of the lower triangle down, apparently an impression from a worn plate, the left margin is wide, the perforation cutting into the next stamp, m¹ in varieties.

With the left frame line split into two parts from the level of the chin up, n¹.

These variations, and a few others easily recognized, not found in the imperforate stamps add to the table:

LEFT. Top Bottom								RIGHT. Top Bottom
X1		perforated along center line						X2
...		extra line inside half way						Y2
...		side line starts thrice						Z2
		extra line	opposite	lower	½	of stamp			w4
		"	"	"	¼	"			x4
		"	cen. of roset. to cen. of stamp						y4
		"	lower block to upper"						z4

The color of all these stamps varies like the unperforated greatly, and the same remarks concerning it might be here repeated.

Perforated Five Cents.

The stamps are 2½ mm. apart between the sides and 1½ between the tops and bottoms; the imprint etc., as before. In these sheets the perforations generally cut into the stamp. They were printed in many varying shades of several colors; dark brown, dark black-brown, yellow brown, red brown, and almost rose.

The second plate was slightly altered. The little projection or salie at the top and bottom was partially or wholly removed, forming the following variations:
