Ok back to the 1982 regular set blackless situation. Since I was reminded of this thread, I have been checking my 1982 cards (they are scattered about, so it is no simple task) and so far have not run into anything them... maybe...
So far all of the examples of the (accepted) Blackless have been either the regular player cards or the All Star versions. None of In Action, Team leaders or Checklists.
When I went through mine, I only have all 6 checklists. 1-3 are "blackless" (ie they are missing the black border around the photo frame) although they may have orange or red frame and 4-6 are normal.
#129 - Checklist 1-132
#226 - Checklist 133-264
#394 - Checklist 265-396
#491 - Checklist 397-528
#634 - Checklist 529-660
#789 - Checklist 661-792
Quick look on ebay active listings, results:
129 - none have black frame
226 - none have black frame, some have light orange frame
394 - all have orange or red frame
491 - all have black frame
634 - all have black frame
789 - all have black frame
Here is an ebay listing (not mine) that has a good look at all 6, you can definately see a trend between the first three and the second three.

I will try to remember to get a scan of the ones I have.
