It's typical for Guatemala. They have very often minor changes on years within the same type. The next type of 5 centavos has 6 subnumbers because of minor changes. I guess those minor changes were more visible (changes in the tree and incuse/relief script) so they got subnumbers while for this type they didn't.

But two different “1”'s within the same year (1971) is a nice find. Well done.

(by the way, the “teeth” on the numbers are called “serifs”)

Tank you

I've enlarged your pictures and made them equal in size. You can use these pictures to make a change request to show the differences in the “1” on the date.
