Coin Rings, or Gold Rings, are ring-shaped objects that first appear in Super Mario 3D Land. They resemble Red Rings but with a yellow color, and they give the player five regular coins when passed through. They are frequently found in underwater courses.
Coin Rings reappear in Super Mario Odyssey, acting as they did in Super Mario 3D World.
