The Gold Tile Turnip is a golden version of the Tile Turnip and, therefore, more expensive. When a plant makes golden coins the other one connected to the golden tiles of the Gold Tile Turnip also will make golden coins. So you need to plant Marigolds in the golden tiles, otherwise will not do anything. If you don't have Marigold, too bad.
