I was informed of this by a very knowledgeable collector/seller. Has anyone else heard this before? I never paid any attention to the numbers (1-80) but it makes sense to me, especially when it comes to the Rosen card.
The answer is damage to the corner at top right was caused by the printing machinery that resulted what is usually called a corner pull. Seen most on one of the top corners, usually the right one and almost always in the first series of 1-80. The flaw in the machinery was corrected later in the printing process.
