can you tell me how this occurs...it appears(to me) that the "bubble" would have formed after the coin was struck as the "date" is below the bubble and it has no part of the date on it. again thanks

“Zinc corrosion (“zinc rot”) can be induced by contaminants trapped between the zinc core and the copper plating. A more common cause of zinc rot is the presence of a small perforation or tear in the copper plating. This allows oxygen and reactive compounds to reach the zinc core.”
