As others have said, don't expect too much. I did have success selling domains on NamePros, but that was almost a decade ago and truthfully I'm not sure if they're as active anymore. I'm sure you can find other domain communities as well.
Quick tip: Don't just post the domain name. Explain why you bought that domain in the first place -- it tends to get more inquiries in my experience. For example, let's say I wanted to sell the domain "bagfullofshit.com" -- Disregarding the novelty aspect, you could explain that you were planning on starting a service that sends pranks to your friends and that you wouldn't be actually sending bags of shit. It gets them to think.
