How could you get a 1976 and 1975 Yankees team autographed ball authenticated and valued?

Answer 1

According to the collector's price guide, "Team Baseballs," your ball is worth between $200-350, with value being greater or lower depending on exact year and players present - in particular, the inclusion or exclusion of Thurman Munson, who died young - plus the all-important overall condition of the ball and Autographs. Other key factors include type of ball (is it an "Official American League" ball?), whether there are any "clubhouse signatures" (autographs signed for players by ballboys, attendants, etc), and total number of signatures present. The authenticity of the Munson signature is of particular importance, as he used "ghost-signers." These factors, plus the authenticity of the all the significant Yankees signatures are the main variables in determining value. An autograph that is not authenticated by a creditable company could sell at half the price or less than one that is. Two of the top, and most trusted authenticators are PSA/DNA, and James Spence Authentic (JSA). Collectors will pay more for signatures authenticated by either one. Check the respective websites Show Schedule to see if they will be in the area that you live. They also do business through the mail. A 1975 New York Yankees Team Signed Baseball with the key signatures: Munson, Nettles, Piniella, Lyle, Martin, Bonds, Hunter, and Guidry is worth about $450.-$600. A 1976 New York Yankees Team Signed Baseball with the key signatures: Munson, Nettles, Piniella, Lyle, Martin, Hunter, and Guidry is worth about $850.-$1,500. Value is based on average prices of recently closed auctions. Prices may vary based on condition, and the type of authenticity that accompanies the Baseball. Prices may also vary based on the amount of signatures, and key signatures acquired. The more complete the baseball with key signatures the more valuable. In a recent auction a 1976 New York Yankees Team Signed Baseball sold for $1,609. Baseball featuring Thurman Munson's signaturehave been on the rise in the last couple of years. If the signatures are not properly authenticated the baseball could sell at half the market value or less.
