The specter of inflation

When stock prices plummet, the entire world is turned upside down. Is another stock market crash coming? Is another period of massive inflation on the way? That is why I am thinking back to the period 1923-1924, when the German Empire faced high inflation. The German Mark plummeted by the day—no, by the hour! This can be easily traced using the stamps from that time. While they were initially denominated in Pfennigs with the highest values ​​being just a few Marks, from 1922 onwards, the decline was extremely rapid. In June 1922, the lowest value of a postage stamp was already 5 Marks and the highest 50 Marks. But in October 1922 the lowest was 50 Marks and in December 1922 the highest value was 500 Marks. By early August 1923, the 'value' of a postage stamp had already risen to 5.000 Marks. The great inflation had begun. Officially on August 24, 1923. In September 1923, another stamp of 100.000 Marks was issued, but by then it was impossible to keep track. A sarcastic joke from that time was that someone boarded a tram at a stop in Berlin and paid for a ticket for a ride costing a few thousand Marks, but people boarding three stops further on had to pay ten times as much! Therefore, no new stamps were printed; instead, existing stamps were overprinted with the value in numbers and letters. The numbers had become far too large. On August 24, 1923, a stamp with an overprint of 8.000 Marks on 30 Pfennigs was issued. On September 20, 1923, an overprint of 250.000 Marks on 500 Marks. On October 1, the overprint 400.000 Mark was printed on stamps from 15 to 40 Pfennig, immediately followed by values ​​of 800.000 Mark and 2.000.000 Mark. Sheets of unfinished stamps were quickly perforated, sometimes with very poor results. But it didn't stop there. By then, the stock of old stamps without overprints had run out, and new stamps were printed. Because of the rosette background, the stamps were soon nicknamed "basket lid stamps"—leaky as a sieve? Thus, stamps of 100.000.000 Marks (one hundred million) followed on October 30, 1923, and 500.000.000 Marks (five hundred million) on November 5, 1923. On November 11, 1923, an amount of 5.000.000.000 Marks (five billion) had to be paid, and on November 22, 1923, already 50.000.000.000 Marks (fifty billion). They did not go any higher. On November 30, 1923, a large-scale monetary reform was announced with financial assistance from the United States, and on December 1, 1923, a new series of stamps appeared. These incorporated the numbers 3 and 5, and the digits 10, 20, 50, and 100 into a new monetary value: the Rentenmark. Named after the Deutschen Rentenbank, founded in October 1923. The exchange rate was set at 1 : 1.000.000.000.000 Mark! The Rentenmark or Rentenpfennig was indeed printed on coins, but not on stamps. On August 30, 1924, the Rentenmark replaced by the Reichsmark and the financial market had become virtually stable at that moment. What happened after that is another story. A nice theme to collect? Stamps with enormously high values? Other countries have also experienced periods of inflation. Which country would have had the highest value on a stamp?
