Little suggestion: Would be cool if in the end of quizzes there would be a special highlight when you actually get a coin you don't have so far. Right now I don't really look at the coins at the end of the quiz because I am only lacking a few. I only know that I got a new one if I see that the total number goes up (if I still remember the old number that is). ;)
I'll keep that in mind! Not immediately, but I'm thinking about a new reveal style at the end of the quizzes, so it'll be a good time for other additions as well!
