One authentic 1910 German 100 mark banknote. These notes are old and are in circulated condition. They may be worn and have noticeable fold marks, marks and stains, small tears along the edges, and other conditions as a result of old age and circulation. Per the pictures, I have confirmed these banknotes to be authentic under a light table, they have a watermark pattern embedded in the paper and thick fibers on one side of the paper. I have also examined them under a microscope. Serial numbers on these bills will be different from those in the pictures. If you have any questions, feel free to ask.
