There is a program called Character Map (Click Start | Run | Type “charmap” and press Enter). It lets you select special characters and copy them to the clipboard. It also gives you the alternate shortcut, which for the cent sign you press ALT + 0162 (Note: the numbers need to be typed using the numpad, NOT the numbers above the keyboard).
Or you can just copy this:
