Paper Abstract

General soiling is the main reason for withdrawing banknotes from circulation. Optical characteristics are fundamental for determining deterioration during automated banknote sorting. A comparative study of the results of the Ukrainian hryvnia (UAH) banknote sorting by optical characteristics was conducted for banknotes withdrawn in 2009, 2012 and 2017. If in 2009 and 2012 due to general soiling, which is the main reason for the withdrawal of circulation for banknotes, 89,19% of the Ukrainian hryvnia were withdrawn from circulation, then in 2017 this figure has decreased already to 50%, depending on the denomination. Thus, the determined before and implemented the direction of priority research and development to increase the durability of the UAH - increasing the resistance to general soiling - has significantly improved the durability of UAH notes, since for other currencies the withdrawing due to the general soiling is 64 - 81%. It was found that the use of processing complexes allows to reliably assess the quality of the banknotes, although there are certain problems: there is a mistake not taking into account the simultaneous presence of various types of damage on one note and the return to circulation of deteriorated banknotes and unjustified removal of circulation of suitable banknotes due to an erroneous assessment of their status to be deteriorated.
