I have an unopened box with some limited addition cards in it. inside the box I'm guessing there is well over 100 cards. On the box it says: "Topps 20 Years of Baseball Major League Baseball The Real One! Bubble Gum Cards Instant Win Vintage Topps Cards Plus Anniversary Sweepstakes Win Complete Vintage Sets 1952 to 1990 Total Prize Value One Million Dollars." Anyway I was planning on selling it on Ebay, but I'm not sure how much it's worth or if it'll gain value if I wait longer.
