Tydligen användes de till ekonomiska transaktioner.

"They date back about 5,500 years, roughly two centuries before the invention of writing. The exterior of each ball contains an "equatorial" seal running down the middle and, often, two polar seals running above and below."

Helt fantastiskt med något så gammalt ...
