1. looks like a grind job 2. & 3. look like grease filled dies.... wait for better experienced opinions...
The 2nd & 3rd are definitely the result of a grease-filled die. I'm not sure about the 1st one, myself. Maybe a better close-up of the 1st coin by itself would help. Chris
The 1st might have been encased and the 2nd and 3rd do look like grease-strikes. That'd make the 1st damaged and the 2nd and 3rd grease-errors.
