Attractive mid grade 1970 Topps set, an especially condition-sensitive set due to the silver-gray borders that are prone to chipping.  The set marks the ringing in of a new decade with the rookie card of Yankee catcher Thurman Munson.  The first Topps issue in 18 years not to include a Mickey Mantle, the Munson card has been the primary driver of the set's value despite the presence of scarce high numbers and a larger number of cards (720) than usual.  This is a pleasing set, the cards lightly handled but not abused, though many are subject to the Topps centering issues of the era.  A technical breakdown of the set is 1% NM, 12% EX/MT, 34% EX, 36% VG/EX, 16% VG, and 1% lesser.  Key cards grade out as follows: #10 Yastrzemski (VG-EX), #17 Wilhelm (EX), #140 Jackson (EX), #150 Killebrew (EX), #170 B. Williams (VG-EX), #189 Munson (EX), #210 Marichal (VG-EX), #211 T. Williams (VG), #220 Carlton (EX), #230 B. Robinson (EX), #250 McCovey (VG-EX), #290 Carew (EX), #300 Seaver (VG-EX), #330 Brock (EX), #350 Clemnte (EX), #380 Perez (EX), #459 Jackson AS (VG-EX), #462 Aaron AS (VG-EX), #470 Stargell (VG-EX), #500 Aaron (VG), #530 Gibson (VG-EX), #580 Rose (EX), #600 Mays (VG-EX), #640 Kaline (VG-EX), #660 Bench (VG-EX), #712 Ryan (EX-MT).  720 cards total.
