Major error eye candy #15: Collar cuds

Yeah, I took a break from posting more entries in this series, but here's another one, prompted by another recent thread.
For anyone who isn't familiar with pictures like these, they're taken with the coin balanced in the bottom of a parabolic flashlight mirror. The edge of the coin is "unpeeled" around the obverse, with the outermost part of the picture corresponding to the portion of the edge closest to the obverse. As you move inward in the picture, you move downward along the edge. The obverse is shown in the center, necessarily in perfect alignment with the edge. The pictures are surprisingly simple to take.
The collar is sometimes called the "third die". Like any other die, it can crack and break. This is a collar crack at about 10:30
A large collar cud from 2:30 to 6:30. (This picture isn't as clear as the others):
A partial collar (or possibly a narrow collar cud) from 4:30 to 9:30, with a large collar cud from 9:30 to 12:30:
A fully split collar. At first glance this looks similar to the collar crack above, with small raised areas at 6:30 and 11:30. What actually happened is that the entire collar split in two, with the whole left side shifted outward as a complete unit. The extra-thick rim makes this look like a small broadstrike or misaligned die at first glance, but it's clearly a full split collar.

Nice eye appeal
i thought some collars were 2 pieces and separated at coin ejection and then came back together? coulda swore i saw an image or video of that?
.
Almost all collar breaks on reeded coins are either bilateral split collars or retained collar breaks. I've seen very few full collar breaks, where the working face actually is lost.

Very cool!
