Amongst items just purchased from SFS, was a strip of 25 of the 2004 WAG issue of the Eagle Presorted First Class Stamps. Included, of course, was Scott #3848, Prussian Blue Background w/Gold Eagle that looks like this:

Uncommon (to me anyway) is the poor impression on the reverse side of the stamp, which I assume was supposed to be a counting number as the stamps were taken from a 3K coil roll:

While it doesn't impact the stamp itself, it makes you wonder why they (the USPS) even bothers to put a backstamp number on these stamps if they can't be read because of the poor quality imprint.
