So, I have a strip of 10 historic flag series stamps. All the pictures I have of this strip shows the Ft. McHenry blue Liberty stamp on top, and the Don't Tread On Me stamp on the bottom, as can be seen here:

My strip is the exact OPPOSITE of this, as shown in this picture

It's clear from these pictures that two different sheets were made. Is there any difference between the two in quantity, catalog number or value?
