I have been selling my second and third sets from 1975-1979. I have kept the very best set of each year for myself. They each average NMMT - with many cards that meet “8” standards and some that meet “9” standards. It is genuinely rare to see raw sets in the shape until you get to the mid 1980s. They will not be cheap but are available for sale if interested.
