Back in the 50's we'd get those back in change all the time, but they was so dark you could barely make out they was even an Indian Head...this one has lots of copper color showing, think it's been cleaned in the past?
It doesn't appear to have been cleaned. My brother has ruined countless wheat pennies trying to clean or "restore" them they all seem to have a pasty or dull finish. I very well may be wrong though.
A full liberty is when you can still see the entire word "liberty" inscribed in the band of the head dress. It's really easy to see once you know what you're looking for
