Here is an example of Tri-X grain from 1991 using Acufine. Scanned with an Epson V700 flatbed - plus how I imaged it back then. I guess that you already know that Tri-X is still being sold. I used both OEM, and bulk loaded - same great stuff.

I prefer the image on the left, there may be less superficial detail, but the white shirt is much cleaner, whereas on the image on the right it as become murky etc.

When I bought my Autocord it came with a bunch of old Kodak Pan from the 60s and 70s. I shot most of it just fine.

Did you buy your Autocord in 1975?

Ok, so this roll was shot at ISO 100 (instead of indicated 400) and dev at 85 w Cinestill DF96. 10 degrees extra equals one stop push.
Question.. one would think that would mean I should just rate it at ISO 50 and dev normally. But I think that only applies if this film was fresh, not 35 yrs old. It seems that the push in dev is what is removing most of the base fog. Eh, dunno...

I don't think I could tell it was expired film based on these.

Nice examples shown here with expired films which worked out well. Here a few examples from my experience with expired films - the photos were taken after the given time in storage (meaning expired films were used to take photos but exposed frames weren't kept in storage long).
Expired Fujicolor Super HQ200 film, likely > 10 years old and kept at room temperature. Taken at ISO 200. The film was more grainy than usual
Expired Kodak Ektachrome 100 film, likely > 10 years old and supposedly kept in fridge by former owner. Taken at ISO 100. Still very good results from it
Another expired Kodak Ektachrome 100 film, likely > 10 years old with unknown storage. Taken at ISO 100. It revealed a strong purple tint with snow landscape photos.
Expired Fujicolor Super HQ 400 film, likely > 10 years old with unknown storage. Taken at ISO 400. Still good color gamut with a bit faded greens and quite grainy.
Expired Kodak Porta 400 VC film, likely > 20 years old with unknown storage. Taken at ISO 400. Some faded colors like blue but significant yellow/orange tint, grainy.
Expired Kodak UltraMax 400 film, likely > 10 years old with unknown storage. Taken at ISO 400. This one performed still very well.

Final attempt w the 35 yr old TriX.
This time I rated it at ISO 50, dev at 80 @ 4 mins (half stop push - normal DF96 Mono is 75).
This is where this batch should be shot at, as the negs were perfect, and zero manipulation was required in post.
If only I could get my hands on more of this, I would be very happy to shoot it at 50! Hint hint...
What it looked like on the light pad:
And I happened to test it (again) in Venice Beach. Where I met Zack who was a willing model!
How the conversation went - "dood, you look great, let me take your pic"
"I love film cameras, sure!"
Nikon N80, 35 f2 D, 35 yr old TriX @ iso 50

Ok my first complete failure - the Agfa APX25. I shot is at ISO 12 and basically no images. It could also be that Cinestill DF96 does not work with it, as even the film leader that is directly exposed to light when you load the camera was clear.
It should have been black/opaque if everything was ok.
Ah well, all I had on that roll was Elvis waterskiing with Sasquatch while being pulled by the Loch Ness Monster.

Next up - Fuji Press 400 and Fuji Super HG 400. Both I rated at 100. No idea how old those are - maybe 20 years?

Didn't get the Fuji Super HG 400 back because the lab by mistake gave me someone else's negs!
I'm hoping they still have mine, or at least they get returned.

Also no frame numbers/text in the rebate area?

whole lotta nuttin. The closest to sumfin was super feint images, so feint you knew something was there but you also knew it was a complete waste of time to try and figure out what.

Second roll of SuperHG 400, this time exposed at 200.
Ok, these look different as I used them (intentionally) in the continuous overlap mode in my LC-W.
The film looks totally fine. Of course I've now used all of this one.
FYI the brownish central tint with concentric lines is why I just ordered a new light pad! This one is worn out after years of faithful service.
