Very hard to value these as the coin market is ever changing at the moment.
Put it on the free marketplaces with a BIN. You could try with "make offer" but I don't think you'd get any as the market is flooded with them. Although, that could work in your favour at the moment. Get it visible and see what offers and interest you get for a few months, and use that info to decide on a BIN or your next move.
