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?

The phrase "put your two cents in" is used to mean offer an opinion or give your input on something. The phrase "a penny for your thoughts" is an old expression that is used to get someone to tell you what they are thinking about. The idea is that a penny is a cheap purchase and that you can get someone to speak their mind for that amount of money. So "put your two cents in" implies offering an opinion while "a penny for your thoughts" implies revealing intimate thoughts for a cheap price. So essentially, the extra penny is going towards getting a deeper look into someone's life and opinions!
