I could be wrong but this still looks like a die crack. An atypical one for sure as pointed out, has some subsidence. If it truly is a die crack, it would be a bi-level crack: http://www.error-ref.com/bi-level_die_cracks_/Which is something I don't think I have ever found, so neat find! |

Thanks Tanman, that is a helpful link. Vertical displacement describes this well so Bi-level Die Crack is what I'll write on the 2x2. Weighs 2.26g Coop Quote:

Not reduced a lot. What does the edge reeds look like on that area? They might be altered a bit if this a cladding? As far as a crack, it seems to be seen on just one side? Thus the thought about a clad issue.

I was asked to weigh in. This is a bi-level (stepped) die crack. Instead of the sides spreading apart, one side of the crack sank in. These sorts of cracks are slightly less common than conventional die cracks.

This was listed on CoC with a note about the Bi-level DC and link with more info on error-ref. The only other bi-level DC's I've seen have been associated with shattered dies so I'm interested in seeing other examples in single DC form. http://cuds-on-coins.com/roosevelt-...946-present/ |

Really like this dime coinhi. You did a great job with the images to clearly show what was going on. Glad Tanman and Mike commented because I was having trouble describing what I was seeing, but that link to the bi-level die crack saved me a lot of time. Mike said: Quote:
...Instead of the sides spreading apart, one side of the crack sank in. ... I'm a little confused though. Are you saying the die on one side of the crack spontaneously sunk in (as opposed to die subsidence from die wear)? Wouldn't there need to be a void in the die for this to happen? Is it more likely that one side of the crack on the die was lifting away instead of sinking in (sort of a pre-cud) and similar to the following description at cuds-on-coins (but before the flake spalls off): http://cuds-on-coins.com/rim-to-rim-cuds/" A large flake spalls off the die face,..." Thanks for your patience and helping me to understand. Words of encouragement are one of the major food groups.

The side of the crack that appears higher is where the die steel sank in as the result of subsurface plastic deformation.

I also wanted to note that there is an unusual texture to the obverse face of this coin. This is seen on the upper ridge of the crack as well. There are lusterless patches that I wonder may have something to do with the unusual die crack.

Thank you Mike for the additional info. (Although it'll take me at least a year to pronounce the term "subsurface plastic deformation" let alone understand the concept. ) Words of encouragement are one of the major food groups.
