Dutch year letter Q+ for 1875
Until 1931 the assayers were personally liable for mistakes in the result of their work. Until 1931 date letters were considered to be their responsibility marks. When in the course of a year the assayer of a certain office was succeeded by another one, as a consequence the date letters of that office were provided with a distinguishing mark. Usually it was a dot, but commas,
crosses and stars also occurred. There are a few date letters bearing two dots; the result of two changes of assayer within a single year.
