I ordered a strip of 25 Bobcat one-cent stamps from USPS which arrived today. The third stamp had plate number P1111 so I cut off the first five stamps (center stamp having the plate number) since I collect PNC5s. I then noticed that the red on all of the stamps on the strip were shifted to the right by a little. Two top back numbers on the strip.
In the following image, the top coil strip is normal. The bottom coil strip is the one with the red color shift. It's a bit hard to see in the image but look at the right edge of the bottom strip. There's a red line which touches the date, whereas in the top strip no colors touch the date. Also, you can see that the red 1 in the plate number bottom strip is thicker than the red 1 in the top strip.

How rare is this?
