A 50.000 Mark German banknote issued in 1922 is not particularly valuable as a collectible, and it has no face value as an obsolete form of currency. The period in 1922 saw the rise of inflation and hyperinflation in Germany as it struggled to pay reparations for its role in WWI.

"Since the banknote is readily available, it is worth approximately 2 to 10 Euros, depending on the condition.
