1923 Agriculture and Science Issue
By 1923, three stamps, the 100h, the 200h, and the 300h with a somewhat simplified design replaced the six original stamps of the definitive1920 Agriculture and Science Issue. It appears that the printers initially took the die for the 400h stamp of 1920 and, among other modifications, removed shading lines from the leaves on the left side of the design to create new 100h and 300h stamps. These new stamps have a cleaner and brighter appearance.

However, the printers continued to tinker with the design, repairing the lettering, the leaves, and other parts of the stamp's image, eventually producing three types of the 100h and 300h, and two types of the 200h.
