The near end of a proof die

[eyesore]

Just cracked a roll of silver quarters and hit a neat find...Not only were there a bunch of type B's, but there is also a crack progression.

What I thought was a just die gouge on the third or forth coin that I looked at (first image) eventually became a pretty decent crack that starts at the base of the left wing, forks to hit the rim at E of United, runs through UNUM, forks again to the rim along M of America and continues part way down the right wing.

The better part of the roll were related to the two coins in the images.

Nice die cracks. Let me correct one item that is often misunderstood. This is a proof design, not a proof die. Proof dies undergo special preparation to give them the smooth reflective surfaces. This die did not receive such preparation.

I missed the verbage when looking at the variety in my CPG. Thanks for setting me straight. I shan't make the error again.

Question: Was it a case of having more raw proof design dies than needed, or an employee error?
