I won tribute matches in Northern Elsweyr, Western Skyrim, and in Stonelore Grove, but I am only getting a silver reward of two coffers. No other match location is being suggested to me in the quest log either.
just want to double check to make sure you played the right NPC
the weirdest case is probably if your above rank 6 and you have to play the novice or expert NPC to complete daily credit, if you accidentally clicked on the proficient one and didnt notice, you wouldnt have gotten credit (some of those npcs are tightly packed and can register talking to the wrong one sometimes)
i have my main house (grand topal hideaway) listed in the housing tours, it has multiple target dummies, scribing altar, and grandmaster stations (in progress being filled out), as well as almost every antiquity furnishing on display to preview them
As mentioned above, when I go to the daily location there are two NPCs with arrows over them, one is Novice and the other is Proficient. I am at Adept level so I play the Proficient NPC. I assume that if I played the Novice NPC that it would not count. Perhaps this is what is happening to you.
