Gold Ring

Gold Rings are objects that appear in New Super Mario Bros. 2. They are similar in appearance to the Coin Rings from Super Mario 3D Land and Super Mario 3D World. If Mario or Luigi passes through one of these, all enemies will turn golden, twinkling effects are added to the game screen and the music slightly changes with "sparkly" sounds added to it. If Mario is in Gold Mario form, he will earn more coins than usual.

Most golden enemies leave trails of coins behind as they move, or even throw coins instead of their usual projectiles and five coins are given for each defeated enemy. If multiple enemies are defeated consecutively (either by stomping on them without touching the ground or using a Koopa Troopa shell), the number of coins earned is 10, 15 and 20 for the second, third and fourth enemies, respectively. After four enemies, 50 coins are given for each consecutive enemy. These values are doubled under the influence of both Gold Mario and the Gold Ring. However, in the E3 trailer of New Super Mario Bros. 2, only 5 coins were given even when golden enemies were defeated in succession.
