There are twenty different versions of the quest Ten Commendation Signets. The table below summarizes all versions of this quest. Note that the ten rows with the comment "war effort only" only exist until the end of the Ten Hour War Gate-Opening world event. The other ten quest givers will be active until Blizzard decides to deactivate them for all realms.
I accept commendation signets from adventurers who have received them in the line of duty. For each set of ten you hand to me, I'll make sure that you receive a significant acknowledgement of your deeds with our people. I also accept single tokens, but at a much reduced rate of recognition. We are much more interested in greater feats of duty, though no feat will be ignored. With that said, I'll gladly take your signets if you are ready to hand in a set.
Excellent! It is no small sacrifice that you've made to earn these signets, and you will be acknowledged for your service appropriately. It's adventurers like you, <name>, that truly make a difference.
Let me know if you have additional signets to hand in; I'll gladly help you out with whatever ones you need exchanged.
