My Mattingly has the print defect and I do not have one with out it..
The 84 set does not have a lot of variations/errors but here is what I have:
a set of the 84 Encased proof cards (66) in which the inset photo is completely in the box ( there is a an error in that set in that the inset photos of Carlton and Mathews are switched)
Card 126, Braves Leaders, with and without errant blue swath under Murphy's name on front
Card 198 Doran, without any black ink on the front
Card 215 Hurst 634 Marshall and 654 Bailor with no Topps or trademark in upper right front
Cards 340 McCrae, 362 Green, with no red ink on back
494 Davis with team name brown or orange
Palmer 750...several versions with differing amount of stats missing on back ( listed in SCD). There is also a front difference, check mark above cap in insert, or not
The Darryl Palmer card # 801, same format front and back as regular issue but card created for movie The Sluggers Wife. Pictures actor Danny Noonan batting No 84 set is complete without it
