From the rainbow chest I have always gotten the coin, nothing else, and I've opened up thousands of them by now. I highly doubt a rainbow chest drops anything other than a coin, and I personally won't believe short of seeing a video.

The other chests (silver, bronze and gold), I've gotten everything from N to SR to Arcana to coins. But rainbow chest is always just a coin.
