Hope someone buys it back for him.
I think that the Kulczyks should rent the medal from Malachowski on a yearly basis.
Malachowski should show up for his payment at an annual Christmas party thrown by the Kulczyks. He should auction off some number of invitations to accompany him to the party to see the medal and the presentation of the rental check.
Of course the proceeds of the auction would go to fund the treatment of the child or future suffering children.
