The 1952 Topps Mickey Mantle rookie card! The holy grail of modern era collecting. Like Willie Mays, this is not Mantle's true rookie card (see 1951 Bowman). However, from a collectors view, this is THE most valuable and sought after Mantle rookie card. PSA high grades sell for hundreds of thousands of dollars and are out of reach of all but the deepest of pockets!
Mickey Mantle rookie cards, and all his cards for that matter, have always commanded a premium. While his career numbers don't quite stack up with some of his contemporaries (but are still hugely impressive), the Mantle/Yankees mystique carries the day. His hard playing-hard living life style, coupled with the Yankees pinstripes, has created a hobby monster.
