I have to compliment Todd on all his great findings and pointers.

Collecting both sets - I agree with the back nuances Todd mentioned and will just add most not all of the time the m101-5s can have that creamy I call it an
“orange burnt hue” compared to a more white on the -4s..the problem is not all -5 have this orange hue making it tricky for the 27 cards in question.. also m101-5s can be white backs adding to the confusion. Fun sets to collect and still underrated.

I also concur on the -4 print indentations and I have a theory they were early run m101-4s. I say that because most of the blank back Stanage portraits you will see have the print indentations. Attached are some fun toughies..
