On the rope after the 3 ropes, let Mario sink, and jump. You should see a green pipe. Go under that, and hold up and jump again.
You'll be in an empty room, with a Star Coin in front of you. Touch the star coin.
Star Coin 1
At the end of the row of tilting platforms is a row of bricks up high with many Dry Bones on it and a coin. Use the bricks tilting with the platforms to ride up to the high strip of bricks. Up here you can make your way to the coin by leaping on Dry Bones or by freezing one and kicking it towards the coin to collect it!
Star Coin 2
Just before the midway flag is a coin high in the air above a tilting platform. Use the ? Blocks to jump up to it.
Star Coin 3
At the end of the rock of tilting platforms with spiked balls dropping from above is a coin up high. You can just jump into this one when the platform is tilted up.

I haven't got all of the stars coins, but I have got all of them in World 1-6. If you have finished the game already you unlock levels in World 9. For example if you get all of the Star coins in World 1, level 1 unlocks on world nine. And I believe that you get another star on your profile.
