Another thought - for me at least, the definitions surrounding "mid-grade" seem to have shifted over time, at least certainly for older cards. Depending on who you are you probably think of mid-grade in the PSA 3 to 6 range. I don't know about the rest of you, but for me in the vast majority of cases - a PSA 6 is going to be a damn nice vintage card. No creases, sharp corners, and decent centering. When I was collecting as a kid, anything with the term "Excellent" in the grade was just that - and old cards that were "excellent" or better were at the higher end of the spectrum. I remember back then, my main concern with 1950's and 60's cards were that they be devoid of major, ugly creases. Even so, I had and loved some cards that did have those creases. Corners were of lesser concern, I did prefer that the cards have 4 of them. Centering I don't recall being something I was concerned about at all as a kid, I recently went back and found some snapshots of some parts of of my childhood collection that I no longer own, and was surprised at how badly centered certain vintage cards that I had and loved were.

I guess it's all about perspective and beauty in the eye of the beholder.
