| 1. A method for determining a condition of degradation of bank notes, comprising:
evaluating at least two different properties of a bank note, wherein the at least two different properties of the bank note
relates to soiling, limpness, tears, adhesive tape, dog-ears, holes and missing parts of the bank note;
assigning, according to the evaluation of the data of the at least two different properties, a certain value to each property
characterizing the condition of degradation of the respective property;
linking the values of the at least two different properties of each bank note with each other by calculating a linear combination
of the values of the different properties, and
deriving the condition of degradation of the bank note from a comparison of the linear combination of the different properties
of the bank note with a given value; and
processing the bank note in a bank note processing device according to the condition of degradation.
