Gold Dice Block
From the Super Mario Wiki
A Gold Dice Block is a Bonus Dice Block appearing in Mario Party: Island Tour. It is obtained when the player finishes a minigame for Bonus Dice Blocks in first place in Perilous Palace Path, or fourth in Bowser's Peculiar Peak. When they use it, the player can roll two Dice Blocks (one is normal, and one is the Gold Dice Block) to go from two to twelve spaces.
The Dice Block reappears in Mario Party: Star Rush, but only when amiibo are used. If an amiibo has save data from Mario Party 10 on it and the game detects a Gold Token before starting Toad Scramble, Balloon Bash or Mario Shuffle, then a Gold Dice Block will be added as an item at the start of the game. Unlike other Dice Blocks, the Gold Dice Block can roll the numbers 4, 5, 6, 7, 8 and 9.
