The cut book ended up working out perfectly. I needed a lot of bills (several hundred), and I needed the paper to sound both thick, non-laminated, and a little worn, so the book pages gave me the depth and almost the texture I needed.
To finish the trick I took a few real bills and put them on either side of the stack, and took about 15 book made bills, crumpled them, opened them back up and put them inside the rest of the stack in intervals.
foley went very quickly, and with a little eq they sounded exactly like they looked.
and now I have a new prop built. :)
thx for the help.
