Out of a box of 2019 BU pennies, I found approximately 200 with this identical forehead crack. Does that make this a variety or just a lot were made with this error before being caught?
That's a die crack. And you found over 200 of them. If you look carefully at them you may be able to show the progression of the die crack. As the Die continues in use the crack grows larger, wider or longer. Get out your 10x and be prepared to spend time looking at them.
You should keep a few sets showing the progression. A few years from now you'll be glad you did. Maybe even give a set to each grandchild.
Great idea! I have two grandchildren and one of them is now hooked on coin roll hunting, thanks to me! Thank you!
