I think this is sufficient and clear.

そこには札束がいくつも入っていた。
There were bundles and bundles of cash.

This concept is what 札束 seems to refer to:
https://en.wikipedia.org/wiki/Currency_strap
Bundling money together with a simple elastic or paper device is as old as paper currency itself. However, measured and standardized straps are a relatively new idea.

Image search.  Not a roll. (at least not principally)

sankoku says かさねて束にした (stacked up and wrapped?). While I guess this might be applied to a rubber-banded roll of bills, this is not the primary meaning, and it would be covered under [2] in any case. "bundle of cash" will handle a bankroll as well.

If you wanted to translate "roll of hundred dollar bills" into Japanese, I don't think this term would do it.

Stab-in-the-dark, I google image-searched 札束 ロール...  Lots of images came back.  The American money is in rolls, the Japanese money is still in stacks ;)  

Perhaps culturally the Japanese don't roll their bills?　ロール 万円札　returns a couple of images from a stock photography site, but otherwise all still flat.
