Yes, they are. But the bills overlap. The sheets can't be cut with the bills so oriented so I'm at a loss to explain the overlapping.
To me the overlapping looks like someone was running them through a copier for the serial numbers. Odd size copier though...
This isn't counterfeiting, you morons! Whenever somebody goes into this bank with a $100US bill, the bank scans the image so it can trace the bill if it turns out to be counterfeit. That's why only the lower half of the bill, with the serial number, appears. This is a standard anti-fraud operation.
