I run into this frequently and don't really understand why it occurs or how. This 1960 Canada cent (1st 2 photos) has what looks to me like a very wide rim. Two photographs of the opposite poles of the coin (same side) are provided for the wide rim coin and for another regular rim 1960 penny. Could someone please explain this...are they simply off center die strikes? Thank you.
It's considered Misaligned Die Strikes.. Not Off Center. It's such a common issue found on thousands of coins if you know what to look for. It could also be a High Pressure strike which would make the raised rim look a bit higher. Sometimes it's so much pressure it would create finning.
