I have a DS set and have CLs with it, but it is my understanding there are no differences between the DS checklists and the standard checklists. However, because of variations among the 91 checklists and the existence of DS uncut sheets, it is my belief that on at least 4 of the checklists you can determine if they are NOT DS checklists. Those being CLs 1,3,4 and 5.
Zach Wheat who started this thread is my go to guy on DS cards. You might pm or email him to see if he can offer more info on identifying DS checklists.
It is my understanding that that the DS CL 1s have Phil Bradley rather than Mookie Wilson as 727. That the DS CL 3 has Carl Nichols as 19 rather than 119. That DS CL 4 incorrectly has Keith Miller as 105 and Kevin McReynolds as 527. And DS CL 5 correctly has Palacios as 348, Lind as 381 and Lavalliere as 537.
