Abstract
An acceptor for money items such as coins or banknotes produces a money item parameter signal x1 as a function of a sensed characteristic of a money item. A store (12) provides data which defines a window corresponding to a normal acceptance range of values of the parameter signal for a money item of a particular denomination (NAW), the range including relatively high and low acceptance probability regions (RAW, USM) which correspond to a relatively high or low probability or an occurrence of a sensed money item of a particular denomination. The processor (11) determines when an occurrence of the parameter signal x1 falls within the low probability region (USM) and then for the next sensed money item compares the value of the parameter signal (x1) with window data corresponding to a restricted acceptance range (RAW) so as only to accept the second money item if the corresponding value of the parameter signal x1 falls within the restricted acceptance range.
