What benefits do note-issuing banks (commercial ones, not Central Bank) get ?

In some countries banknote-issuing banks are responsible for putting aside foreign currency (used to be gold, now it's more like to be US dollar, Euro, Japanese Yen) with the central of banks of their respective countries as deposits when they issue money. As these banks are not creating money by issuing banknotes, can anyone please tell me what benefits do these banknotes-issuing banks get, apart from the publicity they get by having their names printed on the banknotes and that they are being trusted by the local governments ?

1. odds are there are some nice government contracts that make it worthwhile, banks are there to make money, so they are not doing something for nothing/
