I don't doubt your info.

I'm not denying there are fakes or that the Dexter is genuine. I run a commercial laser and the Dexter one shown has earmarks of laser engraving but the arced type should have the same grain lines in it that follows the lower part of the chip.

I'm also careful of calling out fakes myself due to it happening to me in person. I was told one of my chips was probably a fake / counterfeit due to the fact this person had not seen one like it before. The fact is that it is the only one of it's kind and where it came from is known.

I'm not an expert on the style of chips you posted, but I'm always intrigued by odd and unusual chips whether they're fake or not.
