There's no denying that most of us have checked into therapy to overcome our coin collecting addiction in New Super Mario Bros. 2, and with the global coin total hitting an incredible 500 billion, Nintendo Australia has a reward for players who have become coin millionaires in the popular platformer.

So, millionaires, what do you get? Nintendo has an exclusive New Super Mario Bros. 2 certificate to honour those that have spent copious amounts of times collecting coins. All you have to do is take a photo of yourself and your Nintendo 3DS screen showing your 1 million coin tally and submit it to the official website as proof that you have earned your certificate.

Players have until March 31st to submit their entries, but until then, for those of you that need to reach the million coin total can download the Gold Classics Pack for Coin Rush Mode, featuring courses based on the original Super Mario Bros. and Super Mario Bros. 3. You have until January 31st to download this course pack for free.

So what are you waiting for? Get collecting!
