Pre-agricultural tribes could have had forms of wealth — an ornate spear or knife, a prized shawl, a special ceremonial bowl, etc — that they passed down.

It seems quite likely to me that as soon as we started crafting and carrying things around, we developed complex behaviors around who gets which things.

Frequently those things were buried with the people who made them.

It is not really possible to determine who made the grave goods found next to a skeleton (or urn). Some specialization of work is seen in hunters and gatherers already. Not everyone makes their own spearheads or cotton strings etc.
