PSX Tomb Raider Last Revelation USA listed with GH in serial?

I've been submitting the serials reported by psxtools.exe which come from the EXE's name (I would imagine). I had seen several GH games in the DB with it dropped from the serial so I assumed we were using the actual EXE's serial. Final Fantasy Anthology GH has it on its packaging for instance, but not in the DB.

So, should I submit the serial from the exe, disk, or cover if they differ?

The serial is often taken from the disc itself mostly because we have seen some multi disc games where the EXE Date on the disc is the same for every disc while the discs themselves show the intended serials and even show GH for Greatest Hits games. I have also recently come across some games with serials that end in P3 since they came in a 3 pack of games.

Ok, will do in the future and I checked back over my past dumps and luckily, none of them should have had GH in the serial. But, all the Greatest Hits versions in the database that are listed below should all have 'GH' added to their serial:
How do you know that? I don't see you in the dumpers list. Not all Greatest Hits have GH in the disc serial.

Just out of curiosity, what make the Tomb Raider Revelation listed here 'v1.1'?
There are other version of this game, and this one would marked already as v1.1 because of knowing of existing an other one.

I don't know if there's a method for determining the v.# that I should be doing.
You don't need to care about, serials will be set by Mods.

The GH version of Tony Hawk's Pro Skater 2 listed here also has GH in the serial on the disk.

No, I didn't dump any of them. . . but there is still a 99.9% chance they are wrong if redump.org wants to list the serial printed on the disk.

I don't really care to redump them just to prove they should have GH in the serial; if it were up to me, I would just use the serial in the EXE's name and add a 'tag' ([O,G,P,C] etc) to reflect which versions used the dump. I was just pointing the games out in case someone else here cares to fix them.
