The other option is to look about for an unfrequented pawn shop. The pawn shops draw from individual pools of coin, so if you find an untapped one, you'll be able to sell items. Bear in mind, however, as mentionned, that pawn shops pay 1% of the in-game value of the items, so any coin you get from them is likely going to be somewhat paltry.
Best bet? Find people to buy things you can make, or go out hunting for gold.
