<p>[QUOTE=&quot;19Lyds, post: 1838601, member: 15929&quot;]I came across this Kennedy a few months ago with these strange cracks in the fields.</p><p><br /></p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/1964-DKennedyRPMandFieldCracks003_zpsfe3b1635.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/1964-DKennedyRPMandFieldCracks004_zps4b114c72.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/1964-DKennedyRPMandFieldCracks005_zps5a2328f2.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/1964-DKennedyRPMandFieldCracks010_zps0c21c255.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/1964-DKennedyRPMandFieldCracks009_zpsffc616e1.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>Any ideas as to what may have caused this?&nbsp; I mean, cracks in the field but not of the devices??</p><p><br /></p><p>More pictures.</p><p><br /></p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/1964-DKennedyDieCracks001_zps34926482.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>Note the &quot;erosion&quot; flow lines below.</p><p><br /></p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/1964-DKennedyDieCracks002_zpse22e1193.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/1964-DKennedyDieCracks004_zps4599cf38.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/1964-DKennedyDieCracks003_zps7d276ab7.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>For the folks thinking &quot;die polish&quot;, typically, die polish produces parallel lines. Certainly never lines that are perpendicular to each other. Nor lines that form &quot;y&#039;s&quot;.</p><p><br /></p><p>The shape and pattern if the lines almost makes me think that the die was brittle.[/QUOTE]</p><p><br /></p>
