To "cash in your chips" means to sell or exchange something for money, especially when you're done or finished with it. It comes from the practice of exchanging chips or tokens for money in a casino game like poker. When you're ready to stop playing, you can trade in your chips for cash. The expression can be used in situations where you're ready to get rid of something, like a job or a relationship, and want to be paid for the time or effort you put into it.
