In my opinion the original 34 SL players were printed on one sheet or sheets first. The additional 14 came later and were included on sheets with other minor or major league players. This explains why even though the original 34 are available on more backs than the added 14, the added 14 are more common. They were mass produced since their sheets contained major leaguers as opposed to just SLer's. Also this is backed up by the Brown Old Mill cards only showing up within the original 34 group. Just those sheets had the Brown Old Mill printed on them.

Concerning the 48 major leaguers from the Coupon Type 1 set you need to keep in mind that 6 of those are Super Prints, so we're really discussing 42 350 Only players.

With that said I'm not mixing up the SL and ML players. The Coupon Type 1 were printed with front image sheets specific to that back. 68 front images in some order that then had the backs printed on them. They did not in my opinion segregate the ML and SL players onto different sheets for that issue as they did with the first 34 in the 150 series.
