What security benefit is unlocked by varying the size of the bills?
For (very fancy) cloth/paper bills like American ones, some counterfeiters wash the inks out of $1 bills to make $100 ones. Only possible if the $100s are the same or smaller size.

I believe the US made washing much harder with other techniques because of this in recent years.
