Hello coin talk, it was laundromat day but before I left I got me $40 in quarters. the first handful in sorting, I found this. Can't make out the date but you see the one and the nine, the pictures are not blurred that's the way the coin looks especially on the obverse. The reverse looks okay. There's no hit marks on the rim and it's coming from the rim that's why I think it's a giant cud. How do you even search something like this. I began with googling cud. That was like peeing in the wind,oops my bad. So I came out to my favorite coin site to ask the professionals. There seems to be a hit top of the t in Liberty. Thank you
Not sure but it looks like a strike - through (Struck Through Grease from the obverse die). Caked-up grease on the reverse die gets hard & causes the deformity like the picture above (Clipped from NGC website)
It's heat damage, and probably a bubble between the core and clad layer. A cud would show a weakness in the same area of the reverse. It is all damage IMO.
