I've read multiple articles, blogs and opinions and still don't have a definitive answer. And I'm sure all you experienced collectors have read posts about this topic several times so I apologize in advance. I love roll searching. So when I find pennies in such a different range of colors it makes me wonder. Besides looking for key dates, error dates etc. Should I be concerned with colors like below? Left is a normal everyday brown penny we are all use to seeing. The middle is a nice shinny coin. Right is a dark red penny. Besides hordeing older pennies anyway should I keep any separate like the nice shiny one? Or the red one? I promise ill never ask again
