As others have pointed out, there's no way for you to sell that tokens if its not listed on any exchange. I suggest you go back and follow that bounty thread and ask the managers or the devs. Probably we can help you out if you tell us what tokens it is. Regarding selling that token at ICO price? Unlikely to happen though, not unless that tokens pumps hard after its listing on a exchange. So don't put too much hope of getting the price within the ICO price so that you won't get disappointed at the end.
