So this is interesting: I'm an EE, so I look at stuff like this all the time. I have a surprisingly decent chance of being able to identify random ICs I've never before (from major Western manufacturers) by pattern alone.
These almost all look deeply wrong or counterfeit to me, which is kind of unnerving to look at! I think it's mostly the fonts. There's not a lot of Arial or Bitstream Vera Sans (& descendants) on IC packages.
Yes I'm rather disappointed at the lack of effort with the fonts. I don't understand why they didn't just convert an image of the chips to SVG, clean it up, and engrave that.
edit: quick google finds advertised resolution to be 1000dpi for the engraver, so that 4004 die could be within the realm of possibility. Anything more complex probably would not work very well though.
Slate slab coasters from Amazon work really well for this. Engraved a couple of these for myself, like a Taito Bubbble Bobble chip and the MOS 6502 for a friend. They make amazing gifts.

The AD7746 has had enough of an influence on my life that, well, a big one as a coaster/paperweight would be a perpetual source of smiles.
