Arcing rim to rim die crack
A crack that follows a trajectory from one point on the edge of the die to another. The area of the face of the coin isolated from such a crack generally amounts to less than 40% (over 40% evolves into a rim-to-rim die crack). It manifests itself on the coin as a raised metal line that starts from one point on the edge, crosses the design elements and reaches another point on the edge (E.C.13).
In some rare cases, this raised metal line can appear in the form of a branched Arcing rim to rim die crack (E.C.14).
From the moment the die begins to break on the edge, the crack creates a sort of unevenness on the design elements involved. This happens because the die fragment that broke (detached but not totally from the rest of the same) remained inside the beating chamber at the time of minting, still impressing all the design elements. Therefore, between the phase of the Arcing rim to rim die crack and the phase of the Arcing rim to rim die break, a phase called Arcing rim to rim die crack with retained fragment (E.C.15, E.C.16, E.C.17 E.C.18, E.C.19) can further occur.
