Yep, looks molded alright. These are indeed 1940s, call them Chippendale or Duncan Phyfe or Neoclassical revival, probably mahogany. These come from the "golden age of dining sets," the 1940s and 50s. In the U.S. midwest, everyone is trying to sell their grandparent's or great-grandparent's dining room sets, and at this point whole sets are going for $200-$300, so I'd say these chairs would probably bring $20.00-$25.00 each on a good day.
