@All.yaoi.men.are.straight.for.me I'm pretty sure that's the exact reason, the reason to why his step mother's work was sold, because she was a valuable and rich person. Your work cannot be sold in an auction depending on your life value, your position in a government, or whatever power/wealth you hold. And the mother was pretty much a commoner back then, so there would be no possible reason other than this.
