    Wherever you post it, you'll need photos.

    If it is small it is likely a merchant or money changer's stamp, indicating their check for authenticity.

    CBO could stand for anything.

    Just a damaged note. Value is $100. Who knows what the "CBO" stands for ... or cares?

    Once a note leaves the BEP, anyone can stamp or write anything they want on the note. Usually, it is considered to be damage. Bills with the autographs of famous people can add value to the note and are quite collectable.
