From a previous post by @mikediamond about a similar chain strike coin:
Quote:
The flat edge is not a clip. It is where the expanding perimeter of the coin contacted the protruding portion of an off-center coin pinned by the adjacent die pair.
As to the question about a second strike, I think you might be right, but eagerly await the opinions of folks who know more about these things than I do.
