I don't think it was a "jackpot output" ... There's more than one type of box, a lesser (gives 1 mark), a normal (Unknown contents to me), and a greater (30 marks). As the name of this box implies, it was dropped in Gelkmaros. I had killed one of the mobs that drops the Inggison version only to find it dropped nothing. There's no real reason to move to Inggison to farm these boxes as an Asmodian. The honorable marks seem to be there only for you to lose the normal marks you have acquired. The bundle that costs ten of both, and returns 1-100 marks seems to be heavily weighted to drop less than ten, essentially making it useless without really good RNG luck.
