The blanking press runs straight through the strip of metal to make blanks. If the press punches too closely you get a clip. Clips cannot be at angles other than perfectly perpendicular to the surfaces of the coin - end of story.
The coin in question has lettering inside the supposed clip area - impossible if this were a real clip. If the planchet was clipped, that area would have no lettering - just like Bill said.
This coin was hit hard by something after it was minted. There's no other explanation for a coin that has a flattened area on the edge that shows it was obviously done after the edge lettering was placed on the coin. Anyone who argues this doesn't understand the process that made the coin. Anyone who understands the basic principles of the minting process can see this is obviously damage applied to the coin after it was minted. No sugar coating here, just stating a simple undeniable fact.
