Recently, Bob Piazza and I have been discussing trail dies in concerns with master dies and working hubs. There seems to be such incidents on both of those manufactured pieces,. So, why not strike throughs from master die to working hub? I am sure that it does happen, however, quality control pulls must of the blunders, or so I would imagine. Who would want a series of coins, that number in the millions, with an obvious flaw. As James Wiles pointed out, in this day and age, dies (and hubs) are relatively inexpensive to make. But again, I do imagine there is a point where the inspectors of such devices let small, insignificant faults go by.
Looking at the pattern your coin has, it would seem to be struck through a small portion of cloth. Do you have multiple examples of this anomaly? With different dies?
