This is a top-notch ball from the Yankees' fifth consecutive World Championship. The official American League (Harridge) baseball is NRMT with 29 signatures, all in blue ink and averaging 7.5/10. Included in the mix are Mantle, Stengel, Bauer, Blackwell, Houk, Carey, Sain, Mize, Woodling, Dickey, Crosetti, Berra, Martin, Ford, Raschi, Lopat, Reynolds and Rizzuto. No team before or since has ever won five World Series championships in a row, making this very clean ball a very valuable item. The 1998-2000 Yankees were just one of two clubs (along with Oakland) since then to even achieve a "Three-Peat."
