In Skyrim you also have to sell to fences, unless you are stealing from one of a couple/few invisible hidden chests that store the Travelling Kajiit Merchant’s wares, when they are in that town. In that one case, the stuff isn’t marked as stolen, and you can sell back to the merchant you just robbed. His gold is in the chest as well, so you have to leave the gold if you want to sell him back his stuff.
