I love how the front page doesn't scream SOCs/SOMs to you and is just straight up here's the compatible cameras with pictures (with some SOM info below).
I wouldn't be surprised if the bills themselves are marked with specimen or something on the non-visible side. Maybe they're also artificially worn bills produced during bringup or testing.
