Selling rare items to the Wandering Trader

The player should be able to sell the unique items it has in spare to the wandering trader for a good amount of emeralds. Items like saddles, totems of undying, music discs, raid banners, horse armor, special items you find in structure chests or in raids that you have extra, but dont want to throw away because of their value. This would give even more value to the trader.
