I mentioned the other day I turned in my coin cup at Coinstar and got 40 bucks. Well, I've learned something else about these coin machines in grocery stores and some chain drugstores: people don't check the slot for rejected coins. Sometimes perfectly good coins get rejected. I've started checking them when I go to the store. I got 17 cents at Kroger yesterday and 50 cents at CVS two days ago. Caching!
