Similarities and differences of the stickers and prints:
6337 - sticker 1.1 x 1.7, white background, cup shape 1, laurels with gap
6539 - sticker 1.1 x 1.9, transparent background, cup shape 1, laurels with gap
6327 - print on 2x2 brick, cup shape 2, laurels without gap

So 6337 and 6539 can share the pattern (same subfiles) and 6539 adds the geometry to enlarge the background with two quads.
6327 (used in three other sets as well) print looks very similar but is a different cup shape and laurels are cut off slightly differently by cup and have no gap behind cup

Sticker dimensions are roughly guessed, as the reference images are not very detailed and some are at an angle. So the background shape may need to be adjusted. Pattern should be fine.

I already got all three variants prepared with remodelled cups and laurels.

What about subfiles naming? Can a 821435i reference a 170877c subfile? Or have the be named differently?

Merged subfiles, removed category and keywords from subfiles. Changed from mirroring symmetric to inlining geometry fully.

This subfile 170877bs01 can be shared with 821435i. How would the subfile be named so it can be shared between two different parts?

The content of this 821435i would then be like at the end of this message. If you are okay, I would upload it (without the added quads). I am hestitant because this might replace Takeshi's work.
I am unsure if they are the same size or not. The reference photos are not very detailed, so the sides of the stickers are not clearly visible and replica sticker sheets may be off slightly as well. Could be the same or a small width difference. Tendency is same width, so also 1.7

Do they have the same font on the number 1? If so then the 1 could be inlined aswell.
As I wrote in the brick, see the font prims as templates that should/could be inlined.

It's not ok to change other authors files. If Takeshi find your file usable, it's up to him to change his file.
Or, you could use his subfiles in your part.

It's ok to use a subfile in many different parts, exactly like your suggested code do.
It can even be rescaled, if necessary. Subfiles are meant to be reused.

I suggest that you try to use his subfiles.

Inlined number

you could still subfile everything but the center of the cup and cut that in half (use it twice here)
does this need BFC NOCLIP? transparent sticker...

Reduced poly count

Yes, this would be possible as well. Question is what to prioritize. Reduce file sizes / duplicates as much as possible or avoid special treatment like noclip that you mentioned.

* Pattern looks good but as the laurel and the cup look symmetrical it should be split with the number moved to the main part.

* Misses NOCLIP

* Triangulation should be improved:

Symmetric in subfile, asymmetric in main file

Should the symmetric be kept halved and mirrored or not? Halved results in T-Junction and overlap reports.

Noclip not necessary. Don't understand why it was occuring.

I put the effort in to trace the shape more accurately. I also appreciate that Takeshi already did it. His number 2 and 3 are very good and I'd like to reuse these for the white stickers 170877c and d. Then the podium topic is done from my side.

Fixed mesh errors - whatever tool or user in front of the screen messed up again.

* Triangulation looks good.

* What I intended with splitting in half was something like this:
