Thanks for the input. That's what makes it difficult using CoC. Different progressive states of breaks are given a different number even though they are actually from the same die and it's obvious.

I see what you mean, Crazyb0, about the 004 reverse die chip and the possibility of it being used with other obverse dies. That's a bit of a weakness in using reverse die markers for something like this.
It was pretty easy last time, so maybe I will send it to JC and see what he thinks. Even if it is just an earlier/later die state of another listing, it seems it would get its own designation.
