What is the thing to be stolen?

In my short story for this picture, I wrote that she is climbing into/out of a nobleman's home stealing small valuables such as jewelry, gems, shiny baubles, and gold. While she is a thief, she is one whom steals both for her benefit and for those less fortunate who can barely get food on their table, so she'll be selling any valuables at an underground black market and distributing the money to those most in need. :3

Oh so I see.
