How many $100 bills are in an inch?

Good afternoon, esteemed financial experts. I'm curious about a rather unconventional yet intriguing question: How many $100 bills would one be able to stack in a single inch? I understand this may vary depending on factors such as the precise thickness of each bill, but let's assume a standard US hundred-dollar bill for the purpose of this discussion. I'm fascinated by the intersection of finance and spatial organization, and this question has been niggling at me for quite some time. Your insights would be greatly appreciated.
