<p>[QUOTE="Conder101, post: 87109, member: 66"]VERY interesting. I suspect what we are seeing are the "panagraph" reduction lines from the machine that reduces the image from the epoxy model down to the master hub. The cutter would leave a spiral groove or ridge from the center out to the edge. These grooves are normally polished off of the master hub and master die. If the weren't polished off I would think a working die created from it would make coins like that. Reduction lines can be seen on some seated liberty coinages and are freqently found on shield nickels behind the cross, through the leaves around the shield, through the bottom of the white stripes in the shield, and between the stars on the reverse.[/QUOTE]</p><p><br /></p>
