Just to correct the terminology... this is not a "clogged die strike" or a "filled die" error. Those two terms would indicate something present in the striking chamber, and would be otherwise known as a struck through error. Just for clarification purposes. what you actually have is a large die break. A piece of the die fell out, creating a cavity, so when the coin was struck, that particular area would be raised. That is a fairly large one, so cool find. Keep up the hunt!
