If you read the thread someone else mentioned here from Collector's Universe, it is really informative in terms of statistical probabilities of potential 10s out of wax, vending, rack and cello packs. You should look there because he regularly posts his statistics, but based on his selections of cards worthy of being submitted as potential 10s, he is running at sub-5% on every year, every brand, every type of packaging. Several of them are down around 1%. so for a standard wax box of 540 cards, you are looking at potentially between 5 and 25 potential 10s. But most likely around the lower number based on this guy's stats. It is a really good insight into the harsh reality that even though there was mass production of most every year in the 1980's, the quality control (and survival of quality examples) is pretty brutal. Pop open the 1983's if you want to have a fun nostalgia trip, but the chances of getting one of the big 3 in perfect shape is nil.
