I have been looking at some presidential dollar coins (pre-2009) recently and I have a question about the Edge Lettering process that I'm hoping someone more knowledgeable than myself can help me understand. I've read how the Edge Lettering is applied, which is why the placement of this specific delimiter baffles me. How does a delimiter get misplaced this far up the side of the coin without affecting any of the other edge lettering? I'm struggling to comprehend how this could happen. Maybe the machine bounced or something? The delimiter in question is in the last picture. Drop some knowledge on me brethren.
