Congratulations luv, this is equivalent in baseball to going 6-6, hitting for the cycle and making an unassisted triple play all in one game. Uh yeah, that's what you did. And you made those unbelievers (*ah hem*...Rick) and turning him into a believer.
The printing of district and numbers is a part of the printing process. This is possible, because of the sheet becoming out of register during this part of the printing process. The (1) reverse are printed first. Next, the (2) face is printed. Next the (3) districts seal and it's numbers, last printed is the (4)serial numbers. So, your find has value. Nice find.:hail:
