Has gold ever been worthless?

While it’s an exaggeration to say they placed no value on it, they didn’t hold it in quite the same high esteem as the Europeans. For example, there were fishhooks of gold, an application that would be unthinkable to a European. Fishhooks get lost, either when the line breaks, or the fish gets away.

Following the Spanish Conquest, the amount of gold extorted from the natives, and later mined, and brought back to Spain amounted to a veritable tsunami of M1 money supply. A long period of significant inflation in Europe followed. Evidently it doesn’t matter what your money is made of; if there is too much of it chasing too little merchandise, you get inflation.

In remote antiquity, silver was more valuable, perhaps because in pure form it was indeed rarer than gold.
