Real uses of barter: when money fails

-The real uses of barter come when people who were used to money don’t have much of it anymore. Like immediately post-Soviet Russia or Argentina in 2002. Or in POW camps and prisons.
-Early medieval Europe after the collapse of the Roman Empire, and again after Carlingian empire collapsed. People keep accounts in the old imperial currency, even though they no longer have the coins.
-Adam Smith’s examples all come from societies where they did use money as a unit of account, but since it was slightly scarce they would trade in goods until it was more available.

“The law making tobacco legal tender in Virginia seems to have been an attempt by planters to oblige local merchants to accept their products as a credit around harvest time.”
