However, we can say that:
* Public colleges and universities generally had significantly lower tuition than private institutions. A reasonable estimate for in-state tuition at a public four-year college might have been in the range of $500-$1500 per year, though this could vary widely. Out-of-state tuition at public universities would have been considerably higher.
* Private colleges and universities were substantially more expensive. Annual tuition could easily range from $2000 to $5000 or more, with some prestigious institutions charging far higher.
To find a more precise figure, you'd need to specify the type of college and its location. You could potentially find historical tuition information for specific universities through their websites (often in archives or publications) or through sources like the College Board's historical data (if available).
