Clay seems like it would stick just enough, and there are inexpensive scales available that go down to .01 grams.
I've used painters tape as opposed to masking tape, it's more easily removed. Tear a short piece and roll it into a loop with the adhesive facing out. Stick the nickel to one side and the other side to the speaker. Comes off easily.
