I think the dagger is a copy too. There is just NO WAY Rumple would be like, "oh crap I'm dying, better tell Snow and Charming where my dagger is!" I think he set it there to lure Cora and Regina out, he just was not expecting to be injuried by Hook when he would be facing off against Cora and Regina.

We know he hide it the first time in the forest. But then had to move it because August knew its location. He could not have brought it with him to Manhattan because you can't bring pointy objects on an airplane. So its somewhere in Storybrooke.
