Weimar Germany Hyperinflation: The 1923 Papiermark Collapse
Between 1921 and 1923, Germany's Papiermark lost almost all of its value, with monthly inflation peaking near 29,500 percent in October 1923, per the Hanke-Krus World Hyperinflation Table (Cato Institute). The Reichsbank printed notes into the trillions of marks, a 100 trillion mark note among them, before the Rentenmark ended the crisis in late 1923. Those notes are the founding artifacts of hyperinflation collecting.

The Weimar hyperinflation was the collapse of Germany's Papiermark between 1921 and 1923, when monthly inflation peaked at roughly 29,500 percent in October 1923 (Hanke-Krus World Hyperinflation Table, Cato Institute). It is the crisis most people picture when they hear the word hyperinflation: wheelbarrows of banknotes, denominations climbing into the trillions, a currency that could not keep pace with its own prices. This guide traces the 1921 to 1923 collapse, the notes it produced, the emergency money called Notgeld, and the Rentenmark reform that ended it, then explains why Weimar notes are foundational to any hyperinflation collection.
What was the Weimar hyperinflation?
It was the near-total collapse of the German Papiermark, the paper mark, during the early years of the Weimar Republic. Germany had financed the First World War largely by borrowing and printing money rather than raising taxes, and the reparations imposed after the war added a heavy foreign obligation on top of a strained budget. The mark had already weakened by 1921. What turned a bad slide into a full collapse came in January 1923, when France and Belgium occupied the Ruhr industrial region after Germany fell behind on reparations. The German government responded by funding passive resistance in the Ruhr with freshly printed money, and from there the Papiermark unraveled through 1923.
Because prices rose faster than the presses could add zeros, wages were often spent within hours of being paid. The result is the imagery that still defines the era: Germans carrying banknotes in wheelbarrows and baskets, walls papered with worthless notes, children building with bricks of currency. That documented spectacle is a large part of why Weimar became the popular shorthand for hyperinflation. For how it ranks against later collapses, see every hyperinflation ranked, and for the modern parallel that reached the same fourteen-zero scale, see our Zimbabwe hyperinflation guide.
How bad did the inflation actually get?
At its worst, German monthly inflation reached roughly 29,500 percent in October 1923, per the Hanke-Krus World Hyperinflation Table (Cato Institute), a pace at which prices could rise noticeably within a single day.
The table below tracks the documented path from a weakening mark to a stabilized new currency. Inflation figures carry their source inline; the narrative milestones reflect the established historical record.
| Period | What happened | Source |
|---|---|---|
| 1921 | The Papiermark begins a sustained slide as war debt and reparations strain the budget | Historical record |
| January 1923 | France and Belgium occupy the Ruhr after a reparations default; Germany funds passive resistance with printed money | Historical record |
| October 1923 | Monthly inflation peaks at roughly 29,500 percent | Hanke-Krus World Hyperinflation Table, Cato Institute |
| Late 1923 | The Reichsbank issues its highest denominations, into the trillions of marks, including a 100 trillion mark note | Documented note record |
| November 1923 | The Rentenmark is introduced and prices stabilize within months | Historical record |
Severe as it was, Weimar was not the most extreme hyperinflation ever documented. That distinction belongs to Hungary in 1946, where prices roughly doubled about every 15 hours at the peak (Hanke-Krus, Cato Institute). Weimar is the most famous case, not the largest by rate, and we describe it that way rather than overstate it.
What notes did the Papiermark hyperinflation produce?
As the currency collapsed, the Reichsbank reprinted the Papiermark in ever-larger denominations that climbed from thousands to millions to billions and finally into the trillions of marks, culminating in a 100 trillion mark note.
Written out, 100 trillion marks reads 100,000,000,000,000, a one followed by fourteen zeros. That is the same scale as Zimbabwe's later 100 trillion dollar note, which is why the two are so often mentioned together. It is worth being precise about the record: the 100 trillion mark note was not the highest face value ever printed. Hungary's 1946 pengo series reached far higher, up to a 100 quintillion pengo note (a one followed by twenty zeros). Weimar's notes are famous for the story around them, not for holding the denomination record.
Many of these high-denomination notes saw very little use before the currency was replaced, so a surprising number survive today in crisp, uncirculated condition. Uncirculated (UNC) is the top of the letter-grade ladder that runs UNC, AU, XF, VF, F, VG, G.

What was Notgeld?
Notgeld, German for emergency money, was currency issued by towns, states, banks, and companies when official Reichsbank notes ran short during and around the hyperinflation.
When the central bank could not print fast enough to keep cash in circulation, local authorities filled the gap with their own paper money, redeemable in their own area. Notgeld appeared in an enormous variety of designs, from plain utilitarian slips to colorful, illustrated notes celebrating local landmarks and folklore. That variety, combined with how much of it was printed, makes Notgeld one of the most accessible and affordable ways to hold a piece of the Weimar era. It sits alongside the trillion-mark notes as a distinct and highly collectible chapter of the same crisis.
How did the Weimar hyperinflation end?
It ended late in 1923 with a new currency, the Rentenmark, introduced in November 1923 to replace the collapsed Papiermark.
The Rentenmark was issued in strictly limited quantity and notionally backed by a mortgage on German land and industry, which restored the public confidence that the Papiermark had lost. Old Papiermark notes were exchanged for the new currency at a documented rate of one trillion Papiermark to one Rentenmark, retiring the collapsed money. Prices stabilized within months, and the reform is remembered as the moment the crisis broke. For collectors, the outcome is a fortunate accident of history: the Papiermark notes were left worthless as money, which is exactly why so many survive intact today.
Why are Weimar notes foundational hyperinflation collectibles?
Because Weimar is where hyperinflation entered the popular imagination, its notes are the reference point every other crisis is measured against. Three things drive the appeal.
1. The origin story
The wheelbarrow-of-cash image the world associates with runaway inflation comes from 1923 Germany. Holding a genuine trillion-mark note or a piece of Notgeld is holding the artifact behind that story, which gives these notes a historical weight far beyond their modest cost.
2. Uncirculated survivors at an accessible price
Because the highest denominations circulated so briefly before the Rentenmark replaced them, many reach the market in genuine Uncirculated condition. That combination of a dramatic story and top-grade paper at a low entry price is the same formula that makes Zimbabwe's trillion notes and Venezuela's bolivar notes so popular.
3. Depth to collect
Few crises offer as much to assemble. Between the escalating Papiermark denominations and the vast range of Notgeld designs, a Weimar collection can grow for years without repeating itself, and it pairs naturally with other episodes in a multi-country hyperinflation set.
How does Weimar compare to other great hyperinflations?
Weimar is the most famous hyperinflation but not the most severe by rate, and Planet Banknote stocks notes from the other landmark collapses too. The table below compares the four great European hyperinflations by peak monthly rate, with a shop link for each.
| Country (currency) | Peak monthly inflation | Peak date | Highest-denomination note | Shop |
|---|---|---|---|---|
| Germany (Papiermark) | ~29,500 percent | October 1923 | 100 trillion marks | Germany notes |
| Hungary (pengo) | Prices doubled about every 15 hours | July 1946 | 100 quintillion pengo | Hungary notes |
| Yugoslavia (dinar) | Hundreds of millions of percent | January 1994 | 500 billion dinara | Yugoslavia notes |
| Greece (drachma) | Tens of thousands of percent (~13,800 percent) | October to November 1944 | 100 billion drachmai | Greece notes |
Peak inflation rates and dates per the Hanke-Krus World Hyperinflation Table, Cato Institute. Figures are order-of-magnitude, and highest-denomination notes reflect the documented record for each currency. Hungary is shown as a price-doubling interval because its monthly rate is astronomically large. Hungary's 1946 pengo collapse is the most extreme hyperinflation ever recorded; its accounting units, the milpengo and the adopengo, or tax pengo, and a 1 sextillion pengo note that was printed but never circulated, show just how far it ran before the forint replaced the pengo in August 1946.
How do you buy a genuine Weimar note?
Buy from a source-first dealer, and for the strongest guarantee choose a note certified by PMG or PCGS. Both services authenticate a note and assign a grade on a 1 to 70 scale, then seal it in a tamper-evident holder; on that scale, EPQ (PMG) and PPQ (PCGS) certify original, unaltered paper. Weimar notes are common enough that certification is usually chosen for presentation rather than necessity, but it removes any doubt about authenticity. Learn how grades work in our banknote grading guide, and browse certified examples in graded banknotes.

Frequently asked questions
What caused the Weimar hyperinflation?
It grew out of the costs of the First World War and the reparations that followed. Germany financed the war and its aftermath largely by printing money rather than raising taxes, and when France and Belgium occupied the Ruhr in January 1923 after a reparations default, the government funded passive resistance with yet more printed Papiermark. Prices spiraled through 1923 until monthly inflation peaked at roughly 29,500 percent in October 1923 (Hanke-Krus World Hyperinflation Table, Cato Institute).
How bad did German inflation get in 1923?
At its peak in October 1923, monthly inflation reached roughly 29,500 percent, according to the Hanke-Krus World Hyperinflation Table published by the Cato Institute. Prices could rise so fast that wages were spent within hours of being paid, and images of Germans carrying banknotes in wheelbarrows and baskets date from this period. Severe as it was, Weimar was not the most extreme hyperinflation on record; Hungary in 1946 was far worse.
What was the highest-denomination Weimar banknote?
German denominations climbed into the trillions of marks during 1923, and the Reichsbank issued a 100 trillion mark note, written 100,000,000,000,000. That is the same fourteen-zero scale as Zimbabwe's later 100 trillion dollar note. It was not the highest face value ever printed, however; Hungary's 1946 pengo series reached far higher, up to a 100 quintillion pengo note.
What is Notgeld?
Notgeld, German for emergency money, was currency issued by towns, states, banks, and companies when official banknotes ran short during and around the hyperinflation. It circulated locally in place of Reichsbank notes and appeared in an enormous variety of designs, many of them colorful and illustrated. That variety and low cost make Notgeld one of the most accessible ways to collect a piece of the Weimar era.
How did the Weimar hyperinflation end?
It ended late in 1923 with a new currency, the Rentenmark, introduced in November 1923 to replace the collapsed Papiermark. Backed by a mortgage on German land and industry and issued in strictly limited quantity, the Rentenmark restored confidence and stabilized prices within months. The old Papiermark notes were left worthless as money, which is exactly why so many survive today for collectors.
