Few sets in hobby history are as iconic—or as condition-sensitive—as the 1971 Topps Baseball issue. Distinguished by its striking black borders, this 752-card masterpiece was released in six series throughout the year and remains one of the most challenging sets to assemble in high grade. Offered here is a rare 5th Series 10¢ wax pack, wrapped in vibrant blue and authenticated by PSA—one of only 11 examples known to have received this designation. This series features the potential for cards of all-time greats including Willie Mays, Ernie Banks, Roberto Clemente, and Jim Palmer, among others. With the possibility of uncovering high-grade Hall of Famers within, this sealed relic presents both a compelling investment and an irresistible temptation for the adventurous collector.
