Alrighty. Apologies. Should have gone into greated detail. For example the staff that I had looted earlier named "Staff of Sparks" and "Staff of Ice Spikes" for example. I couldn't find anyone to sell them too. Then I did manage to steal one staff " STaff of Arcane Authority". However, I am guessing since that was stolen. But I couldn't even disenchant those 3. I do know what an Enchanting table is. I did go there but nothing happened.
Until you get a certain Perk, Merchants only buy what they normally sell. So, you can't sell a weapon to a Alchemist. You also can not sell items that are marked stolen. Note, an item can be marked stolen just by putting it in a container owned by someone else, then taking it out later.
So, you have to find someone that can buy and sell staffs. I usually don't sell them, so I can't help you with who.
