Mickey Mantle enjoyed a round of golf with his agent and mistress Greer Johnson and relished in the victory by signing the scorecard, "Greer: Sure would like to collect this BET. Your roomy, Mickey "1 putt" Mantle." We can only speculate what the bet was. The note (NRMT), in blue pen, stands alone below the couple's handwritten scoring and has not faded. Other than the necessary crease down the middle, the 6 by 8 card is EX-MT. Ol' "One Putt" shot a 75 that day at the 72-par Harbor Club in Greensboro, Ga. His relationship with Johnson teed off Mantle's family, who have engaged her in litigation since his death.
