100 Mark Reichsbanknote, green seal

The 1908 Reichsbank 100 Mark series remained in continuous issue for over a decade, circulating well into the Weimar period before hyperinflation rendered it worthless by 1923. The green seal variant distinguishes it from the red-sealed 1898 predecessor — a deliberate administrative differentiation rather than a security revision.

Heavily circulated examples are the rule, not the exception. This was working money, handled daily in commerce across the German Empire and later the republic that replaced it.
