S ummary This paper presents a statistical method for estimating probabilities of soiling and withdrawal of bank notes. The method is applied to seven circulation trials of Dutch bank notes of different denominations. The best fitting distribution for the soiling process is selected for each trial and its parameters are estimated. Then the average soiling time and the average life of the notes are calculated. A notable aspect of our analysis is that large differences with respect to the soiling process were found among notes of one and the same denomination in different circulation trials.
