A true piece of hobby history! Mickey Mantle’s 1958 Topps contract extension—signed by Mantle, Frank Scott, and Sy Berger!

The scan above is from Mastro’s November 1999 Fine Sports Millenium Auction, where it sold for $4,119. Here’s the complete item description:
A truly unique document released from the Topps archives over a decade ago. This is the actual contract extension signed by the 26-year-old superstar, giving Topps the right to produce baseball cards with the Mick’s image in 1959. The standard one-page contract extension is typewritten on Topps Chewing Gum stationery and is dated Oct. 1, 1958. It basically states that Mickey Mantle and Topps agree to extend their original agreement dated April 1, 1957, and that all the same terms and conditions apply (meaning he probably got five dollars and a toaster!). Signed boldly in blue ballpoint pen by Mickey Mantle, accepted by Topps executive Sy Berger, and witnessed by Mickey’s agent, Frank Scott. Accompanied by a letter from Guernsey’s, the auctioneers who originally sold the Topps archive. An important document linking the King of Baseball Cards to his maker.
When Guernsey’s auctioned it off as lot BB462 in 1989, they described it as a “Topps extended contract of exclusive 1957 agreement, signed by Mantle on 10/1/58.” It sold for $1,300 ($1,430 with the 10% Buyers Premium).
Guernsey’s also sold the “original exclusive contract signed between Mantle and Topps, 4/1/57, binding for years 1958-60.” Reading the extension, I think the pictured contract just extended the agreement into 1961, and wasn’t about giving Topps the right to produce Mantle’s card in 1959 as Mastro wrote, but, I’m not a lawyer!
Guernsey’s sold 11 different lots of Mantle contacts and checks in their famous Topps Auction; the one I’d most like to see is the original Bowman contract for the 1951 baseball season that Mantle signed on 4/17/1951!
Happy Collecting!
What a super cool collectible. I know $4,119 is a lot of money… but for this one of a kind piece of history, I bet it’d fetch way more than that in today’s market.
