Crews do not think in loose bills. They think in stacks: a band, a height the camera understands, a number on the strap the script can say out loud. CasaNarco's movie stacks are that unit in a pile. New-style hundreds, banded, meant to be grabbed or left on a desk.
Period is a different stack
The yellowed $2 bricks are dressed for the early 1980s, when a two-dollar bill already feels like a prop. Use them for a scene set then. They look wrong on a table that is supposed to be this morning, the same way a new hundred looks wrong in a 1982 office.
A blow is a shape, not a balance
A money blow is bills spread in a fan. It is what you stage when cash leaves a grip, or when the camera rakes across a surface. It is a camera shape. The bills in the blow are the same motion-picture props as the stacks. They are not a pile you could deposit.
The usual build, top to bottom: filler in the bag, full-print stacks on top, one blow ready for the take where someone throws it. You do not need a different shop for each layer.
