There's not much money in "stocks" domains. Far less than you might think.
I believe it's sellable but for $200 max. That's my appraisal If I would bet I would say $99 or $100. (my tools valued it at $7... but I'm less critical as I like mint tea, mint lemonade, everything mint).
Good luck with your sales, and maybe see more opinions on it.
(Edit: haven't considered TM issues, that changes the deal, see below)
