What's a small pottery ball for?

People's most direct guess is toys. From the analysis of various signs of archaeological discoveries, this statement has no foothold. They don't look like decorations either. Because these small pottery balls can't be worn on people, there are no holes in them to tie a rope padlock.

It won't be a hominid projectile. Because there is no need to burn the pellets into hollow, solid pellets are more durable. Nor is it a tool used by wizards for divination and sacrifice. The findings of archaeological excavations show that this explanation is useless. Could it be a symbol of people's wealth at that time? This has to be proved by more archaeological discoveries or verified by various studies. At present, historians can only describe the number, shape, ornamentation and other external characteristics of the discovered ceramic balls truthfully, and cannot hint at their essential attributes.
