@Danomite early state die crack
@Danomite Thanks for the response.
@Inspector43 It looks like a typical chip in the die. With every design, there are points in that design that are high stress targets. They are prone to early failure relative to other parts of the die. Things can exacerbate that to: material hardness, the hardness of the tooling, angle of the die set, contact, die stage, shimming in areas under the die. I'm sure I'm missing a number of potential causes.
The wear-and-tear manifest in different ways at these stress points: cracks, chips, breaks, etc. Could be minor...might be catastrophic. But what ever it is, it'll show up on the coin. LMCs are known for the cracks from the corners of the Lincoln Memorial. And all about the columns too.
