"Dark hills" vs. "light hills" Collectors use to divide this type into the "dark hills" and the "light hills" subtypes. The difference between these subtypes is caused by vertical shift between the green and brown printing plates. However, there exist a range of different shifts in both vertical and horizontal directions. Some collectors also distinguish the notes printed in dark brown and light brown. I believe that "dark brown" print is the result of oxidation of "light brown" print. "Dark/light hills" and "dark/light brown" occur in all possible combinations.

"dark hills": green plate is shifted up.

"light hills": green plate is shifted down.

green plate is shifted to the left.
