Set of 3 Vintage Miniature Molds

This is a set of three possibly copper miniature molds. I’m not sure if they were for decor or actually used for baking. On them is pictured a bunny, wearing an apron with a broom another one is a cat wearing a cape and holding a picnic basket and then finally a dog wearing a bowtieand carrying a backpack. I tried to take pictures of where there is tarnish or blemishes on the molds.
