solid copper Jefferson cups & large goblet bowl, vintage punch set

1970s vintage CopperCraft Guild solid copper Jefferson cups (roly poly tumblers) and a large goblet shaped footed bowl. I believe this is a punch set, but I think these pieces would be lovely planters / vases.

The tall master bowl is about 5 1/4" tall overall. The four cups are about 2 3/4" tall. These are shiny and bright, but do have a few spots / tarnish marks, and some light scratches.
