I can't find this item in PSA's Pop. Report

Yep, looks like the lowest grade of the Carews. Even though it kind of looks like they hid the pop report in the normal Pop Report search, you can get to it by using the Cert verification, then scrolling down to the Pop numbers on the page, then clicking on the hyperlink on "Population". Looks like the comic is required for the Rod Carew Master set.

Some reasons they may stop grading an issue:
1) They can't tell the difference between real and counterfeits
2) Their inconsistent grading of an issue makes it a liability to their grade guarantee.
3) The set wasn't properly licensed.

I'm not aware of counterfeits of this issue, so that would be weird. You may have to email them and ask, if you're willing to wait weeks to find out. Or call them early in the morning and they'll try to call you back.
