arghi,
Not very long time ago, I posted a few photos showing stamps used in USA by "Georgers" (those that go after "georges", one dollar bills) and their website Where's George:

I also do use a small stamp in about 1/4 of the bills I register. Although I know for sure that most people just don't look at the banknotes, and if they see anything they just don't care, it makes me feel weird to give two or three or more banknotes to someone, all with the same stamp on them...

Here you can see my stamp, and you also have a link to a document by ECB concerning "grafitti" on banknotes that you can read in german just switching the "en" letters into "de". You can find the letters in the middle of the series of numbers.
Read my second link about what and where to stamp the notes (which in any case is nothing else but a personal opinion).
We all have seen stamped notes come out of ATMs, and even from bank recirculating machines.
Actually, the fact any local bank retires the note of circulation, DOES NOT NECESSARILY MEAN that this note is going to be destroyed. Central Banks (or Federal Reserve Banks - FRB in United States) have far more sophisticated machines to determine suitability of banknotes, and most of the ones retired by local branches end up back into circulation.
