Got another one of BC's stealth notes. But this one has his initials over the serial number because stamped notes have trouble going through the change machines in the casino. I sort of suspected it, but wasn't sure if it was his. Now I know better.
Great idea though. If you can't stamp, write your handle or initials over the serial number, and that will clue us in to the fact that it is a stealth note.
