It's 28.83 mm which is the size of a matron head. Comparing it side by side with a regular one, it's actually like a big 1845. All features are bigger, not just the size. I think it may be an early counterfeit. Question is, why would anyone counterfeit a penny? If they counterfeited a dime they would have increased their profit tenfold. And why would they make it oversize?
