Question: what are unopened baseball cards worth?
Answer: Typically, there were 500 cards in a cardboard box and 24 boxes per case. They were sold primarily from the 1950's through the early 1990's. Vintage vending cases, still unopened, can sell for tens of thousands of dollars while those from the 'overproduction era' of 1987-1991 often selling for $200 and less.
