The Debate Over What Money Is, in 3 Minutes

Nomisma means 'something that exists by agreement'.
This is where our school gets its name.
A gold coin of the same name kept its purity for 700 years.
In the 11th century, the gold content secretly started to decrease.
Idea one: The value of money comes from the metal inside it.
In places where trust didn't reach, money reverted to being just metal.
Idea two: The value of money is decided by everyone's agreement.
In some towns, the balance in a ledger book itself became money.
Both ideas are powerful. One in situations where trust disappeared, the other where it was established.
The two ideas were looking at different sides of the same thing.
On the eve of 1948
The answer is: 'Money is a promise you can believe in'.
Paper backed by the state was rejected, while cigarettes, ordered by no one, were accepted.
2009
An experiment in money that doesn't belong to a country. But its price is measured in dollars.
It doesn't fit neatly into any box.
700years
The number of years the Nomisma gold coin maintained its purity.
A country has lost a war. There's paper money officially backed by the state, and there are cigarettes, which no one has ordered to be money. Which would you accept as payment?
Pick one
The paper money, though officially backed by the state, wasn't trusted by the people. An order alone couldn't make it stand as money.
In reality, cigarettes, which no one ordered to be money, became money. What people believed in was what passed as currency.
It's not about the metal, nor is it a state command. Money is a promise you can believe in. The 2000-year debate didn't end with a winner and a loser, but with the two ideas coming together.
