-WAG here. Looks like form inserts from a stamping die or a mold. Are they threaded from the back side? Does a file skid across a corner or does it bite?
-Are they worth anything? Only to what they go into. If hardened they can be ground to a precision size if you have a surface grinder. Other than than they're just a scrap block of unknown material. JMO

Are they light weight, ie made of graphite?
Might be an electrode for a die sinking EDM

Seven or eight of us trying, changing the results each successive one sees. I was getting suggestions that the TC32 referred to a Brothers machine. The TCB could be torque (or torsion) control bolts.

Anyone try calling the #?

Acme Tools claims that’s their old website, formerly known as Tool Crib of the North . So you’d be looking at prior to 1999 for a purchase date.Metalworking Tools | The Tool Crib

Edit to Add: ok, apparently I was not clear enough. I am very skeptical of IA, and don't trust anything it tells me. As I was getting nothing useful elsewhere, I tried to waste some energy by specifically asking AI about the text that was on the box, and suggested it might be machinist tools. ( Who knows if the parts actually belonged in the box)
While there may be some facts in what they supplied, I am not a machinist, don't work with or spec anything for CNC work. I included the links that AI supplied as their sources, in case someone sees the kernel of truth, and can run with it. I personally think there might be some bit of truth in the results, as the results suggested a triangular base, and the OP photo showed a triangular base, and I did not supply that information.
Now, back to my original message, as supplied

TC-32: Insert Geometry and Size
"TC-32" is typically a code for the physical dimensions of a Triangular (T), Positive Rake (C) insert with a specific size designation (32).

Summary of "TC-32 Grade TCB"
If you are looking at a specific insert labeled this way, it is likely a Tungsten Carbide Blade (TCB) or an insert for a Tungaloy TCB holder with a TC-32 (Triangular) geometry.

TC-32: Insert Geometry and Size
"TC-32" is typically a code for the physical dimensions of a Triangular (T), Positive Rake (C) insert with a specific size designation (32).
- Size "32": Represents an insert with a 3/8" inscribed circle (the '3') and a thickness of 2/8" or 1/8" depending on the specific standard (the '2').
- Common Variants: You will often find TCMT-32 or TPC-32 carbide inserts used in turning and boring operations.

You read this is an AI result based on the words on the box, right?

Tungsten carbide grade 32. TCB is a manufacturer designation for the part. Just at a guess, I would say support pad for a specific machine.

Some of us read the AI results, and try to use them as a warning not to trust them. Apparently people have not noticed that I am not a fan of AI.
But sometimes they might have a slight tip of truth that might help someone else have an ah hah moment.
TCB could be Tool Crib. I'm with @seber. I think these are feet or locators of some sort.
As an amateur machinist, these look familiar to me. Like they are roughly the size and shape of other things I use. Like maybe a Tee nut or a vise key or a clamp pad (they could be that). Point is, whatever they were for, if they were left over I would 100% put these in my toolbox for some rainy day project where I needed something this shape.
When you become a machinist, despite whether you are paid or not, you quickly learn that any piece of metal you dispose of, will be the EXACT piece of metal you wish you had on the next project. Its uncanny wisdom passed down over generations in the songs of our people.
The song my people sing to me by our fires sounds like this:
"You threw away material you needed, dumb ***"
"Now you have to pay for material you threw away, dumb ***"
"When will you learn your lesson, dumb ***"
Then there's the verse:
"You are a dumb ***, dumb ***. You are a dumb ***, dumb ***..."
There are MANY verses.

Every machine shop or tool room I've seen has always had a shelf or rack dedicated to small material remnants from previous jobs. It's a bonus if the raw material you need for your current work can be found on the shelf, is close to finished size, and requires minimal effort to complete.
I agree with previous comments, those blocks are likely tungsten carbide wear inserts that are ground to finished height once installed. It should be easy to determine if they're carbide (they are file-hard and rather heavy for their size, and usually a grey color).
