Gene, Was the Wills chip chopped liver!? Not only did Maury autorgraph 2 chips, he added his uniform number, NL MVP '62, his lifetime batting & fielding average, a listing of all his team by position, 1962 NL & AL season standings, the World Series box scores for all games played & for good measure, the 23 Psalm. That was on the obverse. On the reverse he wrote all of the words to "Take Me Out to the Ballgame", the National Anthem, & Annette Funicello's hit of that year, "Fabian, Fabian! You Surf So Good". I would say that the piece you have is rare even by Archie's standards!
