To find a relevant salary, you'd need to specify the location and other relevant factors mentioned above. You could try searching online archives of newspaper articles from 1980 in specific locations, or looking at historical data from teacher's unions or government agencies for that state. The National Education Association (NEA) might have some historical salary data, though accessing that may require some research.
