Welcome to CT. There is usually a discussion on what is a die variety such as your cud cent and an error. Since the die is broken away in the cud spot, it is a die variety. The first variety of your coin is the perfect coin without a cud. Then the second variety is your cud coin. Additional separate cuds make for interesting die varieties. There could be hundreds or thousands of the cud variety. It is interesting to find the first coin when the die broke, then when the broken die chip fell out and produced the cud and finally when the die struck a coin just before die failure. It would be interesting to find a progression of the cud variety. Some collectors look for progressions. Enjoy coin collecting.
Here's a quick edited image of the OPs coin. The S, T and part of the A in the word STATES on the reverse are not completely formed directly opposite of the cud.
Haha. Android phone apps. Circle Cutter to make the picture round and Multi Layer to combine the images with a 40% transparency setting for the top images.
I don't believe she was trying to describe the Blakesley Effect. In her statement: I think 'opposite' here may be interpreted as the reverse of the coin instead of the opposing rim where you would see the Effect on a clipped planchet. And if I understand her correctly, then yes she's correct - the metal would most likely be forced into the broken obverse die (cud location) instead of into the directly opposed reverse die details since there would be less resistance from the broken obverse die.
WELL I'll admit it. I was fooled on this one..good job on the Photo play. I was "OMG I want that!" then read further... KUDOS!
