Another beautiful quality 50,000 Mark Reichsbanknote, from Berlin, originally made in 19 November, 1922. This beautiful, multi-coloured bank-note rapidly became worthless, as the bank-note demoninations ran up into the millions, as the German hyper-inflation was engineered and implemented by the deeply unwise people at the German Central Bank at the time. The First World War reparations had to be paid in *gold*, so there was no advantage to Germany to inflate its domestic currency, to reduce the require war-cost payments. The German Central Bank simply had a bad economic model, which suggested that a certain "British-pound value" of currency had to be kept in circulation, to keep the economy operating. So, as the exchange-rate with the British Pound deteriorated, the reactive-response from the German Central Bank, was to print ever larger amounts of currency. This pro-cyclic strategy substantially accelerated the devaluation of the currency, but it did effectively to maintain full employment.
The Central Bank in Germany, at the time, took great pride in its ability to fabricate and distribute ever greater physical quantities of cash. There seemed to be no understanding - until the entire place fell into a rather curious abyss of economic collapse, which induced France to invade the Ruhr Valley (Industrial heartland) of Germany in January of 1923. By the fall of 1923, a dozen eggs which cost 1/2 a Mark, in 1918, cost 4 billion Reichmarks by October of 1923. This inflation rendered this 50,000 Mark note from November, 1922, essentially worthless. But for a while, it had been real money.
What is truly hilarious, is that I paid $20.00 (Canadian) for this bank note, in May of 2021, as a historial artifact, given that it is in basically mint condition. It is in a collage of other bank notes, in a frame, on the wall in my office. It hangs near the worthless stock certificates and debentures, which I found among my father's legacy: (Common shares in "I.O.S - Investors Overseas Service" and shares and debentures of "International BankCorp Limited" and "Value Capital Limited" - also completely worthless, except as historial artifacts which give evidence to the routine fragility of financial schemes.)
You can hold cash, shares, and/or bonds and debentures. Holdings of each of these asset classes carries risk - and sometimes, that risk is very substantial. You think you possess wealth - but after some time has passed, you only possess a historical artifact. And in these modern times, you might not even have that! :)
