A wax box can span many different years, sports and types of cards. Unopened wax boxes from Topps baseball cards are very famous and go back many years to the 1950's and before. The older unopened wax material is still available for sale, and there is a large selection on Ebay.
Some of my favorite wax box material is 1970's and early 1980's wax boxes from any sport. Baseball, basketball, football and hockey cards have unopened boxes. Also, there are non-sport boxes and golf and soccer and even other types of boxes.
These offer collectors an opportunity to get a random selection of cards within the set of the year of cards, which can allow them to get more than one card in the box of their favorite players. One unopened pack could have that all important card, and one pack may yield two of them. Exciting indeed.
Listed below is current unopened wax box material for sale on Ebay.
