The overprint on the 1 Mark stamp was produced in two types. In Type I, the denomination is positioned lower relative to the stylized flowers; in Type II, the denomination is level with the 'flowers'. Furthermore, Type I exists in two perforation varieties: 14¼ x 14, the most common perforation, and 14¾ x 14, the rarest perforation.
The 6,25 franc stamp was also issued in two types. In Type I, the letter B for Belgien is printed exactly below the digit 6 of the value denomination; in Type II, the letter B for Belgien is placed further below the letter F for franc. Type II was exclusively available at the philatelic counter of the main post office in Berlin and was not for sale at the General Government of Belgium.
Incidentally, the 6,25 franc stamp was not available at all post offices in the Government General of Belgium. The stamp was only sold at the counters of the post offices in Antwerp, Mons, Brussels 1, Liège, and Namur. If someone wished to purchase the stamp through another post office, it had to be ordered in Brussels first, with the amount due having to be paid in advance.
Both the 1914 and 1916 series of overprints were initially valid for postage in the entire occupied territory of Belgium and Northern France, but with the issuance of the series of overprints for the 'Etappengebied' on December 1, 1916, the two series became invalid for that area effective December 15, 1916.
