Has absolutely nothing to do with the ammount of rubber bands. Is simply a wad of cash with a rubber band around it. These types of "Banks" are usually found in illegal transactions; i.e., drug trafficking. The term is also an oxymoron of sorts, because the terms "Rubber Band" and "Bank" imply drastically different levels of risk.

A rack of Benjamin’s so fat in your pocket that a money clip can’t hold it, so use a rubber band instead.
My boo thang’s rubber band bank roll gets everyone’s attention every time he takes it out of his pocket...
