It's difficult to imagine that it wasn't recorded well before it even reached the vault. Firms like Garda inventory cash in excruciating detail as a matter of standard procedure, since otherwise it would rapidly disappear into employee pockets.
Considering how ‘cost efficient’ they were being on security, hard to imagine they were maintaining detailed databases of each serial number for this cash. These are the same folks that bitch and whine over $.25/hr raises for their employees.
There are machines for this. Garda absolutely has them.
They just didn’t have them installed here for whatever insane reason.
