Itma. This looks more like ACSC 102 rather than 100. Notice the numeral thickness. To me, this is a Die III.
Concerning your other question on the duplication varieties listed in ACSC 100. My 2014 copy is probably just as good (or bad) as yours for showing this feature. Below, I've tried to show the very subtle issues with some of the letters. First is ACSC 100(1)d, "Duplication of TRAL". Note that the R has an odd shaped top.

ACSC 100(1)e is, "Duplication of AUSTR". Note the small issues with the S and T.

The last one I tried was ACSC 100(1)f, "Duplication of ALIA". This one has odd bottoms and the top of the I.

If someone has better pictures or explanation, please post.
Note: It is very possible that the latest version of ACSC actually has these numbered different. They do that as new varieties appear.
