<p>[QUOTE="Robert Ransom, post: 4502619, member: 97872"]I have researched this issue recently and determined, to my satisfaction, there are two basic cases for die cracks/breaks. These two terms are used interchangeably and mean the same thing and it depends upon who wrote the article. A retained die crack is a fissure that has been developed in the die due to the great pressure exerted on the die and the majority of the time, this fissure is filled with the coin material. A variation is catastrophic die crack is when the die develops multiple fractures and the result is a myriad of fissures. This type of crack is normally caught, but some get through. The second case is the bi-level die crack. This type is when the result of a die crack pushes one side of the fissure further into the coin causing an upper and lower position of the material to either side of the crack.</p><p><br /></p><p>This is my explanation as I understand the issues.[/QUOTE]</p><p><br /></p>
