Can you ask your attorney if he can do something called an offer of judgment on the beanie so that your ex will be on the hook for the attorney fees going forward. Find the value of the beanie. Send him an offer of judgment telling him you didn't take it, don't know where it is, here is proof of the value of the same, and you are offering it to him so he will leave you alone now and forever. If he doesn't take it and sues you and gets less, then he has to pay your attorney fees. I just looked up your state and it seems to have a statute recognizing the concept. I've used it successfully before to resolve complex litigation, so it should do just fine for a beanie. Offer a little more than its worth (or double) to make sure the finding is less.
