Animate the banknote copies as rigid groups with their internal markings attached. At frame 0, position each of the four bills lower by a different amount than where it sits in the provided SVG and set the tilted top bill horizontal, about eight degrees counterclockwise around its center from its provided-SVG angle, so all bills are centered and perfectly overlapped and read as a single banknote. Then move the copies upward with eased timing into the staggered vertical stack shown in the provided SVG: the lowest bill moves up only slightly, the next bills move progressively farther upward, and the top bill rises the most. As the stack opens, rotate only the top bill clockwise around its center back to its angle in the provided SVG so its right side dips, while the lower bills remain level and appear mainly as layered bottom edges beneath it. Hold briefly at the lifted, tilted stack, then reverse the motion: the bills move downward with eased timing and collapse back into perfect alignment, while the top bill rotates counterclockwise back to horizontal. End with all bills overlapped again as one flat banknote.
