There is a big difference in scarcity pricing for Post and Jello cards from (particularly) 1963. I know there's a slight difference in the red stat line. Other than that you can't tell the difference between Post issues or Jello issues.

If there wasn't a red line difference would there be any price difference? Would we even consider them as separate issues?

I think about issues like Hostess panels from the 1970's. They were issued on different products and the prices reflect scarcity for the overall product, but we don't differentiate between the products, even when panels are issued on multiple product lines.
