At first glance to me those look like standard GM steel "Rally Wheels" with chrome beauty ring. Check the dimensions and offset. GM used them as a "sporty" steel wheel on a variety of cars dating back to the 60s, so certain collectors may value them higher than others depending on what those dimensions are...
Edit: I looked again and they look more like standard steel wheels.... I need to drink more coffee before I respond!
