3What would you do?
You are a merchant in America before banknotes were standardized. A customer tries to pay with a 1-dollar bill from a bank in a distant town you've never heard of. What do you do?
Pick one
Accept it at its face value of 1 dollar.
Back then, notes from distant banks were accepted for less than their face value. Even if they weren't fake, their value was lower because of the effort it took to verify them.
Accept it at a discount.
This happened often. The discount wasn't because people thought the note was fake, but because it cost money to verify it.
When banknotes are standardized, you don't have to verify them anymore. The history of money is also the history of reducing the effort of verification.
You can say why having many kinds of notes becomes a problem.
Can explain the birth of the banknote, from the goldsmith's deposit receipt to the "discovery of fractional-reserve lending."
Can contrast the death of a paper currency (the Confederacy) and its rebirth (the Rentenmark) as a matter of credit design.
You can start this course without reading any other course.

What comes back at the window decides itConvertible or not turns on whether metal comes back at the window. Inconvertible is not weaker; it builds trust differently.
When paper money appears, war finance is usually nearPaper systems are built after the disorder. The system does not create trust first.
Having many kinds is itself the problemThe very labour of checking lowers value. Unification works less by fighting forgery than by sparing the check.
Paper is also a physical thingA note is made of two layers, trust and matter. Burnt, it is nothing — so survivals do not show circulation.
The Goldsmith's Receipt — Another Origin of the BanknotePaper passing from hand to hand in place of gold coins. And the discovery that 'not everything would be withdrawn at once'.
The paper that swallowed a nation — John Law's experiment"Money does not have to be metal." A correct insight, lacking discipline, burst along with the entire nation.
Green Paper, Vanished Paper — Two Banknotes of the Civil WarTwo papers from the same war. The paper of the victor became an ancestor, while the paper of the vanquished lost its promisor.
Redesigning from Scrap Paper — The Curious Revival of the RentenmarkBacked by a mortgage on land. One trillion marks exchanged for one. The moment that proved confidence can be engineered.

The republic and the escudo (2) Portugal 1925 An inspection table in Lisbon This is a case where one could say the paper itself was neither genuine nor fake. The notes were printed with genuine plates, on genuine paper, using the official process, but they simply lacked the authorization for issuance.
Banknotes, in half Greece 1922 The exchange window The banknotes in circulation were cut in half down the middle. The left half became currency at half its face value, while the right half became a 20-year interest-bearing bond. The text even describes the mechanism by which only those who lived on cash were directly impacted.
Notes that promise no exchange China 1375 The printing works of the Ming baochao This paper was designed to be inconvertible to either silver or copper coin. Please follow the logic of how this design—making no promise of convertibility in the first place to avoid a bank run—made the third issue of banknotes weaker than the second.
