the Tmax100 is 8/2020
the TriX is 1/2022

EDIT: I don't know if they're meaningful, but the code before the date are:

Tmax100: 1021 001
TriX: 1011 013

EDIT2: The Tmax400 rolls I haven't developed yet are 0159 001 06/2021

Just checked the Tmax400 roll listed above, and it has three tracks for 6x9 as well. I'll try to get photos of the three papers if its helpful. The Tmax400 rolls were bought from KEH (I had another order, and figured I'd throw it in) in February of this year, for a trip I was taking.

Here is a photo of the three papers. you can see that they are identical except the markings for the emulsion on the left.

some old Kodak for comparison and fuji Acros I. Fron top to bottom, Plus-X, Tmax 400, both mid 90s I think, Vericolor 400 of unknown age (found in a camera I bought), and Fuji Acros from the last batch they made.

Thanks for that.
The top 3 of the older backing paper are, of course, from the time when Kodak made its own backing paper.
