I couldn't find this addressed using Mr. Searchy. I am finishing up my 1960 set. I have put/together/sold or kept 1961, most of 1963, 1964-66 and 1968-69. Gosh, it's hard to find centered cards for 1960 more so than the others. Maybe it is the horizontal design but the presence of diamond cuts, etc. really complicates putting together a 7-quality set. No problem finding the bigger names (if you're willing to pay) but the Felipe Alou-level guys are tough to find. Perhaps there was a more-than-usual placement of semistars on the corners of the sheets. I can't do totally centered and probably will settle for 75-25 or so.

Even a lot of PSA 7s from that year are off centered more than other years (or off register). YMMV, I guess.
