Lucky Nintendo Set
From Nookipedia, the Animal Crossing wiki
The Lucky Nintendo Set is a collection of two statues in the Animal Crossing series that first appeared in Animal Crossing. The set consists of gold and silver trophies of Mario and Luigi from the Super Mario series. It is possible to get these items through codes released by Nintendo Power, which can be redeemed by giving Tom Nook the password for either statue. When the code is entered, he will say "Oh, yes. This prize just came in from Nintendo Power." There is another code to get them, but it appears to be won from a glitch; when the special password is finished, he will say the player won it from a contest, but the contest's name is glitched letters. Additionally, the Mario trophy can be won from the monthly Lottery that Nook holds and the Luigi trophy can be bought from Crazy Redd for 28,000 bells.
