I notice that Bay 1 is one of the more common places on the Reverse for these die breaks. Why is that? What is so different, structurally, about Bay 1? (I wish this wasn't such a scudzy coin!)

i have wondered that also. I suppose that logically - it suggests that stresses are greater in that area than other areas. the stresses could be a function of other characteristics of the coin - even things occuring on the other side. I am certinally not a expert - and the true experts probably hae some - real answers (other that prue conjecture).

the same question may be asked about die breaks or cracks frequently found around the base corners of the memorial building.

all in all - a good, thoughtfull question.

Interesting idea! Well the T fits that area perfectly. However, I do not see why the T would exert more stress than the Y would in Bay 2.

Concerning the corners of the Memorial, I notice that they are fairly close to the outer edge of the coin - could be some weakness produced by that.

Mike Diamond mentions a bit on interior die breaks on his site:
http://www.error-ref.com/?s=memorial+die+chips
But he doesn't mention the Memorials though.
I enjoyed his comment on the difference between a die chip and an interior die break:

Quote:
Any void encompassing an area of 4 square millimeters or more qualifies as an interior die break.
Any void that covers less than 1 square millimeter is a die chip.


But the information about BIE's maybe the cause for the reverse die to be affected there. Not an overlay image of the clash target area on the Memorial cent:

The letters from LIBERTY intersect on this area. (bay one and bay two) So the reverse die could be damaged on this area during clashes. If there were several event that happened to the die, the die must breakdown on this area. I've seen a progression in two rolls I found one time:

Thanks, coop. I had not noticed that definition. Using that, this would not be an interior die break. So what would it be if it is greater than 1 (die chip) and less than 4 (IDB)?

(This one is approximately 0.5 square mm so it would be a chip).

I am not convinced that some of those IDBs on cuds-on-coins would qualify either. It seems that the definition might be considered a bit arbitrary. Maybe it seems that way to me because I do not see the logic behind it being instead of 4, say 3 or 5. I suppose it is good to have a precise definition anyway, just so everyone is speaking the same language!

Now that makes sense to me!

I guess to me it would matter on how wide the chip would be. A crack is a thin line. A chip is wider than a crack.
