A Mickey Mantle autograph might be worth anything from $300 to $50,000 as of July 2014. The worth of sports memorabilia and autographs can be estimated based on a variety of criteria. These include the item on which the signature is made, the particular item, and whether or not the item comes with a letter of authenticity.
As of July 2014, Mickey Mantle-signed goods cost between $300 and $350 for baseball cards with printed autographs, close to $1,800 for an autographed hat from the New York Yankees, and $1,200 for an autographed baseball.
A highly costly Mickey Mantle signature was valued in 2008, according to Leila Dunbar of Leila Dunbar Appraisals and Consulting. The ball, which was autographed by Mickey Mantle, Babe Ruth, and Roger Maris that year, was valued between $30,000 and $50,000. The state of each player’s signature was essential to understanding this item’s value. This is the only ball that all three players are known to have autographed.
