The Hungarian 2 kr imprinted postage stamp is equivalent to 4 fillér which, together with the 6 fillér stamp, makes the correct postage of 10 fillér.
Such use of the postal tariff reply card was theoretically irregular, but the surviving material shows that these cards were accepted.
The mixed use of the krajcár and fillér stamps were possible for 9 months, so fortunately we have several beautiful mixed frankings left.
This period (01.01.1900 – 30.09.1900) is one of the most popular collecting periods of Hungarian philately.
The 6 fillér stamp of the 1900 issue was issued in four colours, the history of which is quite interesting, but I will tell you about it later.
