The coin has a "coin alignment" i.e. opposite to the American "normal".
And what we're seeing here is "ghosting". It's a very minor effect, not really considered a "mint error" as it tends to appear on many coins of the same design. It doesn't usually attract any kind of collector premium.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
