Going borderless like that is extraordinarily striking for US currency, but I bet that would be the first thing to go, as it's expensive to reliably print borderless designs in sheets and then cut them up, unless the designs tile perfectly.

That and other nitpicks aside, if these were our new dollar bills I'd be perfectly happy. They represent a great amount of boldness and brushing away stodginess while still being totally reverent to the heritage they're supposed to represent.
