I collect a lot of different ticket themes. I started with all Mark McGwire HRs. I need only about 14 more to finish that set. I also collect all Jim Thome HRs and need about 20 to finish. That being said, the cost of getting every ticket slabbed would be cost prohibitive. In fact very few of my tickets are graded. To use PSA's population report to determine how many of a certain ticket still exist is not a good idea. as already mentioned milestone tickets probably get sent in many times more than other tickets so that would skew the numbers towards them. But I feel most set collectors do not get their tickets graded.
