your coin is covered in plating blisters caused by contaminants in the mix, no collector value...http://www.error-ref.com/?s=plating+blister
Could you be a kind soul and find one just a little bit bigger? My poor eyes strain to see this one...
It wouldn't be a "cud" as, at least from your description, the anomaly has no association with the rim. However, please do post a photo so we can take a look.
You posted this seconds before I did my previous response; my apologies... The only thing I'm seeing is (most likely) simple staining, Dustin. Unfortunately, such a coin would carry no additional value or premium. Welcome to the forum.
Probably nothing, but "appears silver" is pretty vague and is mostly meaningless. Try to post a few in focus photos of decent quality.
