You can just sell a certain number of stolen items a day

There are the boxes that you can loot from Thieves Troves that have to be opened before you can sell the contents. Could it be that you are seeing those unopened in your inventory?

Thank you for your answers but none of these answer my question i am afraid. I checked both laundry and fence tab while i had more than 12 stolen items in the inventory. None of those appeared in any of the tabs.I havent sold anything yet there. Regrettably, I have no stolen items in my inventory right now as I had to make space last night. I thought maybe my thieves- guild level is too low to fence, or there are unwanted items from the trader. I will make a run to gather some items and then I will post a screenshot for you to check it out. Thank you

Too long ago for me to remember about the Thieves Guild Fence and whether or not he is available to you if you have not done any Thieves Guild quests -- but perhaps that is the reason.

In any event, try to sell the stolen items at any Fence in any Outlaws Refuge. They should take your items.

You do not need to do any quests to launder, you need to do some quests to do heists however.
And yes this is weird. Items outside of the boxes from the thief troves should be able to clear, some items like treasure maps can not be laundered only clear.

Just so you know, stolen item caches Usually have to be interacted with in your inventory and stolen goods have to be taken out of the cache (with stolen ones, make sure no NPCs are looking as it will incur a bounty. If it is a laundered cache which are usually earned from thieves guild dailies, you’ll have no trouble from NPCs and can be opened in front of them)

You open the cache and take the items out of it and then, if it’s stolen, speak to a fence about getting them sold/laundered. If items in a “laundered cache” are retrieved, see a normal merchant about selling them since they are already clean. (Alternatively, clean items from a laundered cache can be held on to as the thieves guild dailies may involve giving a client specific clean items on occasion.)

Tip: With fences, they have a number of slots for selling/laundering stolen goods, once they are full, you gotta wait around 20-24 hours before you can sell/launder more. slots can be increased by upgrading the “Trafficker” legerdemain passive.

You should be able to sell things right off the bat to any Fence in any Outlaws Refuge
You don't need to have even started the Thieves Guild DLC for this.
You cannot sell stolen items to Merchants unless you launder them through the fence first.

As previously mentioned, make sure you first open any containers of stolen items you pick up. You can't just sell the container from your inventory. I can't remember what these are called ("Stolen Goods" maybe) it will be a white named item with a crate icon in your inventory. You will also be caught stealing if you open it in front of NPCs as far as I can recall, so do it somewhere you won't be seen.

Also as mentioned, you can only sell a limit of items per day. This will reset when the server refreshes overnight.
The Trafficker skill in the World>Legerdemain tree effects how many items per day you can sell/launder.

Also bear in mind that if you have a stack of items - EG. Lockpicks x10 - if you fence these it will count as 10 items, not 1.

Just a thought: you haven't "locked" any of them in your inventory have you? If you have unlock them and they should show up to sell.
