Why do you have to “put your two cents in” when it is really only a “penny for your thoughts”? Where’s that extra penny going to?

That extra penny is just a figure of speech, indicating that you should share your opinion even if it's just worth a small amount. It’s an expression which implies that even though your opinion might be small or unimportant to some, it still matters and is worthy of being heard.
