That definitely looks like the 5x205 bolt pattern of old VW/Porsche/karmann ghia. I don't recognize those particular wheels, but I'm also not a VW guy, I just have a friend who is. As long as they are not badly bent or chipped they most likely are not just scrap. It's hard to tell from the pictures, but that center looks like a true magnesium wheel. Or it could just be dirty aluminum. I'd suggest looking to the old VW/Porsche/karmann ghia crowd, you might have some gold, or at least a spare wheel, that someone has been looking for.
