Holy cow! Enormous obverse clash (to be that visible in these pics), and the biggest die break I've ever seen the Mint release on a 3CN. This one is right down the center of my personal interest alley.

The reverse die is actually in two pieces - note the denticle displacement at 3:00. The coin actually looks out-of-round there. I think it clashed so hard the reverse die broke, this coin was one of the first struck thereafter, and it slipped through before they pulled the die.
