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 expression "put your two cents in" originates from the old days when a penny was worth far more than it is today. This phrase means that you should offer your opinion or input even if it's not expected or requested of you. It has evolved over time to mean that even if your opinion isn't desired or necessary, you should still give it anyway. So, technically, you don't have to "put your two cents in" since it's technically two cents' worth of input even though it only amounts to one penny. That extra penny, however, is likely never going to be seen again!
