http://www.vfthomas.com/USpostagest...twocents.htm to describe "diagonal line under scroll above "U.S." as Continental Printing (or American Printing)


under UV lamp


left und right stamp, the left stamp is light mottled?


compared to left is middle und rights is right stamps from first pic, bottom is left stamp

i mine all stamp to by #156? (diagonal line under scroll)

If you can see a diagonal line at the left scroll, it must be #157. But not all #157s have the so-called "secret mark". Some do, some don't. A better way to separate 146 from 157 is by COLOR. #157 is always (or nearly always) a darker brown color than #146s, which are lighter brown. But if the stamp DOES have the diagonal line, it must be #157.

hallo bill weiss, can by left stamp a #157a? what is this for perforation?

thanks @bill weiss

That is the point.





To the extent that the top layer was a thin soft paper, the thin paper stamps we know do not fit this patent, but it is not improbable that a reverse paper process was used with a thin hard paper on top and a thicker soft paper below. Sloane comments that the 2¢ Continental brown double paper is frequently mistaken for the American soft paper special printing (Scott 193), which is not known used.
