The most valuable issue of Life magazine is the April 13, 1962 issue featuring Liz Taylor and Richard Burton on the cover and featuring baseball cards of Mickey Mantle and Roger Maris. Joe DiMaggio appeared on the cover of the May 1, 1939 issue, which is also quite valuable.
Life magazines featuring prominent athletes on the cover are typically among the most valuable issues. In 2014, the Joe DiMaggio 1939 issue typically sells for approximately $150. The Mickey Mantle cover from June 25, 1956 can fetch up to $100. The rare Topps Roger Maris and Mickey Mantle baseball cards inside the 1962 Liz Taylor and Richard Burton issue are the primary reason it fetches as much as $200, not the celebrities on the cover.
