When you look at what happens to a die when a
Cud appears, you are shocked at what happened:

Note how the outside edges of the dies were affected? A big loss of metal on that area. How does the happen? When the die breaks away it is not a single strike episode. It starts with a single crack. Then the single crack connects with a second crack. Then it forms a
Retained Cud:

Somewhere down the line that area will break away and then a
Cud will happen:

While this is not the same die, but you can tell that a lot broke away to form this
Cud coin.

So a
Cud is a large area breaking off of the die. As on your coin it is not anything like a real
Cud. But I thought you might need to see what the die goes through, before a
Cud actually happens.
