How many dollar bills can I fit?

If I put 1 ID + 5 credit cards (1 in each outer slots/pockets), can i fit about 12 bills in the center pocket and be able to take them out easily?

Welcome Of any leather is made.? Is it a pigskin

Description includes "money clip", but that's a different bi-fold wallet. How do I know I'm getting the non-money clip version?
