Is this a new die crack??
Is the crack from the throat to rim for this S-185 something new?
From Breen's description of 1798 S-185, Encyclopedia of Early United States Cents, pg. 532:
Die State VI- Cracked from rim to throat, later extending across the neck and hair. Reverse crack beginning at IC
Die State VII- The crack of state VI extends to the base of B.
Congrats on the late die state!
Thanks, I didn't see it described specifically in the Noyes book (perhaps I missed it), and
I shoulda looked at my Breen, which I admit I don't do very often. It does look like Breen
has more details on die states?
This is part of a radial cracking pattern. First, the crack from the forehead to the rim thru Y formed. Then there is the crack from the neck to rim, seen strongly in your coin. Also in your coin, is the crack in the hair, pointed toward the B of LIBERTY. These cracks seem to radiate from a point behind Liberty's ear. There are also some light cracks in the right obverse field. Apparently the die was removed from service before further cracks formed. Presumably the latest die state also has a cud over I in AMERICA on the reverse.
The neat thing about that crack is that it's exactly the same "Wave Curve" as the S-239...elephant trunk....only lower....
I think, being an old engineer, that the curvature in cracks is a result of maximim shear forces being distributed on the die's surface. Shear forces are also why when you twist a piece of chaulk, it breaks at a 45 degree angle. Maintaing a constant angle of the break, due to the same shear force, along the surface, is what gives the break curvature. Of course, I could be totally wrong too!! Its been 40 years!! The mind is the second thing to go, and I don't remember what the first thing was!
