I just came back to the game and have a bunch of these. I was planning on trading them in for 7th year gifts but just wanted to check in with you guys to see if there was any reason I should not do that.
7th year gifts are the best bet for the really rare minis, most everyone already has the 1-5th year, and the 6th year tonics were pretty much a bust (minus a few of the green and gold ones).
