vintage jello molds, ring mold collection copper aluminum pans kitchen wall hanging

Lot of four vintage jello molds or baking pans, copper colored aluminum. I think these are probably anodized color, not copper plated - there’s no trace of tarnish though these molds are 50-60 years old!

They have a little scratching / wear, but they're gorgeously bright. Each one is a different design, sizes are 8 1/2" to 10" overall diameter.
