It's not 5 dots, it's 6 dots (a full braille cell). And the $100 isn't 5 sets. It's one set, a large gap, and another set.

"The currency denomination must be recognized easily, thus the banknotes use full braille blocks (or cells) of 6 dots, ⟨⠿⟩. The $5 bill has one cell, with the $10, $20, and $50 denominations each having one more cell than previous. The $100 bill has two cells arranged such that there is a space of two empty cells between them"
