Here’s a rare one not seen at all. 2013 retained cud. Displacement seen at ends of the die break on rim.
It is a rim to rim die crack(pre cud). But when that crack shows vertical or horizontal movement (as this coin shows) it is called a retained cud. If the rim to rim die crack bisects the coin, it’s called a bisecting rim to rim die crack. http://cuds-on-coins.com/rim-to-opposing-rim-die-cracks/
I think there is a small cud also. Below the A and to the right. 2nd photo. In the first photo it's at the top.
Understand now? Write it down - Retained/Pre Cud Basically. A Die with that part cracked and hasn't fallen off yet. When eventually it does fall off then there will be a full-blown Cud on the coin. Unless a mint employee catches the cracked die and replaces it. It's kind of like a cracked molar that hasn't fallen off yet.
A retained pre cud is a lot different than a cud. It still looks like a rim to rim die crack to these old eyes. But I can see the die was close to breaking off completely.
Nice addition for my shield cent error album. these must’ve had a short life span striking planchets I think.
@Collecting Nut the first three arrows from the bottom show the void between the surfaces, yes that usually means a die crack. But this image shows it as a step and not raised on both sides. This is clarified by the fourth arrow pointing to the rim. The notch shows that there is an elevation to the area, and the chunk of die has seperated.
