chzman is probably right but I'd need to see the other side.
If the other side is normal it is possible that the weak 4 is the result of uneven pressure due to a slight misalignment or as he wrote, a grease-filled die.
Whatever it is...I'd keep it. It's kind of interesting but it is not likely to have any value over face. I like finding those kind of coins...but I don't buy them. Go figure.
