Adding to the question of value. Anakin did not sell C3-PO for his and his mother's freedom or food. The novel mentions they are close to the breadline with some quote about qui-gon seeing she was concerned about how to feed extra hungry mouths.

If the Jawas were selling to people who were unable to pay more then there is a good chance that they would sell the droids off world instead as there seems to be a reasonable transport network.

The droids Jawas sell are assumed to be good quality as Owin was angry when the first astromech purchased broke down. He didn't inspect the droid before and took the droid on faith.

The only explanation I can think of is that these droids are considered collectors items. R2D2 particularly was heavily involved in the destruction of the Death Star.
