Those look like Native American grinding stones. If the round stone and the bowl shaped stone were found together, that is quite a nice set. They used the stones to grind the grains and seeds that they would then cook or bake into their foods. They would use them much like we use a mortar and pestle. Google it to find images that match yours.

Value? Depends on who is buying and how bad they want it.
