Action Comics #1000 was first published in the US earlier this year.
I got the impression that this seemed to be an unheard of before milestone. Most likely due to the fact that such a daunting number might prevent newcomers from getting involved in a comic book series, publishers use retcons, reboots and restarts to wipe the slate clean and also restart the numbering (and of course you can sell a new issue #1).
So it might actually have been a rarity.
This discussion - rather rude in places, imho - seems not to be clear on how to go with having an answer to this question:
Problems seem to be:
Are Japanese Manga comic books?
Is 2000AD a comic book? (currently on issue #2086 - its wikipedia article calls it a comic magazine, which in turn is a less fancy term for a comics anthology, which both Action Comics and Detective Comics at least started out as.)
Are The Beano (currently on issue #3949) and similar publications comic books?
To me, they all seem to be comic books (or at least anthologies, which Action Comics started out as, too), but maybe my intuition is wrong there. My own subjective defintion would be:
- Cover (with Artwork)
- One or more stories
- Misc stuff: e.g. letters to the editor, advertisement, maybe an editorial or an interview with one of the artists etc
But that could be wrong and an official definition might actually exist (maybe back in the day, due to the US censorship laws one was made?).
After all that preface, here it is:
Which comic book series did indeed go from #1-#X and which X is the highest?
