Sly Cooper and the Thievius Raccoonus

You will find 99 coins before the end of the first chapter. Finding 100 coins will grant you another life in the game, so once you gain an extra life the trophy should follow. If you die or fail a mission, you will start from the beginning and the coins will reappear once you come back to life. Breaking all the signs and other breakables and killing enemies will get you this trophy a lot faster then just collecting them.
