For this very rare variety this is a very well preserved 1 mark 1940 Lodz Ghetto banknote.
Numbering in six digits, no series designation, numbering print in orange, a sequence of numbers starting with 28XXXX , i.e. this is an early printing of this denomination.
According to our opinion, two different colors of ink were not used when printing the numbering, the influence on the different color of the numerator over time was probably the paper used for printing itself, and in the case of the 1 mark denomination it did not differ in weight (as in the case of the 5 mark 1940 denomination, where we have cardboard paper and then we have the numbering on it in orange, and on plain paper we have the numbering in red), because all known varieties of the 1 mark banknote are printed on plain paper.
Mr. Jacek Sarosiek, in his catalog Banknotes of the Lodz Ghetto 1940-1944, Bialystok 2012, in the chapter on the analysis of the paper itself, mentions two types of paper for printing Ghetto banknotes. A wood type of low quality, easily worn out in circulation and, in addition, with its tendency to change color, and a cotton type of paper, i.e. with cotton fibers added to the paper pulp as a much more durable paper in circulation. And it is here that one should look for the reason for the different colored numbering on the bills of the Lodz Ghetto, which appeared over time.
From our observations of the listing of this variety (6-digit without series printing), we noticed that orange numbering occurs in the initial printing of this banknote up to a certain number sequence in the numbering, where after that we only have printing with numbering in red.
Visually nice state of preservation.
Near the center, a single, clear fracture and two lighter ones to the right of it. Double, fracture of the upper right corner, otherwise no remarks.
Natural. Without conservation.
