Do many classic commems have die breaks?

I was looking at some coins today and saw a Pilgrim with a huge die break, is this common on commems? I just have not noticed a break on a commem before.

It seems extremely unlikely that a Proof would have a die break.

Not only is there a Columbian proof die crack, but the die crack is used as one of the key diagnostics to tell whether you have a true Columbian proof (rare), or just a prooflike MS (somewhat plentiful in nice PL).
The diebreak is readily visible if you know where to look, like this Heritage Columbian proof photograph, horizontally at the very bottom of the large sail, between the first and second ribs from the right (on the sail above the spot). Yes, that's a crack in the die, caused at the beginning of the proof run from so much pressure and multiple proof strikes. It's not visible on MS strikes as shown in this MS photograph.
