The piggy bank grenade does not appear in the files of Fallout 3, but it can be found in the book The Art of Fallout 3. It is a grenade version of the bottlecap mine because, as the name suggests, it would have used currency for shrapnel. Unlike the bottlecap mine or the Nuka-grenade, the piggy bank grenade appears to use a powder fuse rather than an electronic one.
