Alright here's a penny for you. There is obvious doubling on it. Very heavy on the date also in Liberty also in the back on the e on one and e on cent. also around lincoln's face bust... etc. and strangely sometimes the doubling is to the left (mint mark) or to right (date) ok i cant find a coin like this anywhere. first can someone explain why this doubling happened? Then can someone please explain what kind of doubling it is? Thank in advance to all of you for your polite, educational, constructive future posts. Remember not all of us know what you know.
