Put it just before the reveal in an edit, then follow it with a bell ding for the payoff and a vine boom when the result lands. That order keeps the coin moment first, the reward second and the reaction last, so each beat has its own place in the sequence.
Über diesen Sound
Matthew Coin is a short, single-purpose sound built around a coin idea, lasting about 1.7 seconds from press to finish. It lands as a brief, light lift, the kind of small payoff that makes a payment, a win or a joke feel finished. It works best as a quick punctuation mark, not a clip to sit with, and it keeps its focus on that one coin moment.
