These unopened packs of 1967 and '70 OPC baseball cards (both GAI 9.5 GEM MINT) feature two issues with a no-frill sensbility. But both yielded cards of amazing value. The white-bordered '67's boasts numerous possibilities for those taking a chance on a virgin deck. You could land a rookie Tom Seaver; or future Hall of Famers such as Mickey Mantle and Brooks Robinson. The gray-bordered '70s also came in vertical format and, among the more valuable assets are Roberto Clemente, Hank Aaron and a Thurman Munson rookie card. Though years apart, both wax wrappers employ a similar orange, red and white color scheme but note the difference in price. Yup, buying, trading and flipping doubled to a nickel.
