Got this mysterious penny in my change today. It's yellow and the feel of it isn't right. I had been buying some titanium nitride coated bits this same color at the hardware store, and my first thought was that someone had TiN coated a penny (for some reason). But then when i picked it up the weight felt off, so now i'm imagining someone fed the machine at the penny factory the wrong metal. . . . . . . #coin #cent #penny #errorcoin #brass #titaniumnitride #numismatics #numismatica #numismatic
