lot of 70s vintage copper molds, tinned solid copper jello mold collection

Lot of vintage tinned copper food molds, all 70s I think, made in Korea and Japan.

The ring mold is 7 3/4" in diameter, the heart 3" across, the rooster about the same size as the fish at 11" long.

These are tarnished and spotted, though the tin looks good (not at all worn) on all. A good polishing would probably help these a lot!
