Salt was so valuable long ago that soldiers were sometimes paid with it.

The longer version

Every person needs a small amount of salt to keep nerves and muscles working, and before refrigeration it was the main way to preserve meat and fish through winter. Demand was constant, supply came from only a few places, and it was heavy to move, so it commanded a high price.

Rulers who controlled salt works or taxed the trade had a dependable income, and paying troops in something they could always sell or eat made sense when coin was scarce. The word for a soldier's pay in several languages grew out of that practice.
