I have seen far worse brandable domains got sold for 4 or 5 figures, and far better ones for less. There really aren't any rules. It's frustrating, yeah.
So, my opinion. If you think its a good name, than it is. Make something out of it, a brand, a blog or etc. And then sell it for a hefty price. Or just keep the profits and grow.
On your questions. I would start by listing it on Sedo with a make offer or buy it now price. You can then try putting it also on brandable domain marketplaces like Squadhelp and Brandbucket. But don't expect to be accepted there or even make a sale right away, it could take some time, or even forever...
Best of luck!
