Here is a new find i had tonight, it is so small but it its a cud also im not seeing it on cuds on coins website.
I would not call it a CUD. Looks more like a High Pressure strike that caused the edge to rise up a bit and cause a bit of Finned Rim (Finning)... Then the Finned edged folded over on itself, so it would not be a CUD... IMHO You also see a lot of Die Deterioration going on
