Who sold Joseph, and for how much?

Jubilees says simply that the brothers plotted to kill Joseph, changed their minds and sold him to Ishmaelite merchants. Jasher gives a price: the sons of Jacob sold him to Midianites for twenty pieces of silver, and the Midianites sold him on to the Ishmaelites for the same sum.

The Testaments of the Twelve Patriarchs let the brothers speak for themselves, and they do not tell it the same way. Simeon says Judah sold Joseph while he and Reuben were away, and that he was angry Joseph had been let go alive. Gad says that he and Judah sold him for thirty pieces of gold, hid ten and showed twenty to the others. Zebulun says he had no share in the price, and that Simeon, Gad and six other brothers spent it on sandals so as to tread it underfoot.

Joseph's own testament adds that a eunuch of Potiphar's wife later paid the Ishmaelites eighty pieces of gold for him.
