You need to sell the right things; from what I've seen, ore, wood, hides sell pretty well at all levels, mainly due to experienced players with lots of gold levelling up alts and not wanting to gather materials. The other loot items, like skins and furs, or task items (barring some rep items) don't seem to sell at all. Check to what is selling and see what you have in the same categories.
If you find yourself alone, stood in a stone circle with the sun on your face, do not be troubled. For you are in Middle Earth and it will soon be time for 2nd breakfast!
