<p>[QUOTE=&quot;i2i, post: 3509215, member: 102748&quot;]This is not for those who refuse to question. It&#039;s not for those who dont look deeper into meaning. It&#039;s not for those who say, &quot;it is because, it&#039;s always been and I say it&quot;. Lol</p><p><br /></p><p>When a die has an engraving error WHY would people expect it to ALWAYS be equivalent to the intended, in regard to depth and quality?</p><p>I mean their could be incomplete engraving error types of die doubling that effect the die?</p><p>Ok. What I&#039;m referring to is the double dies that must be part of the die, not part of the process. Therefore, double dies are uniform varieties, which collectors seek.</p><p>This is not disputed.</p><p>However, it is known that some double die varieties also have die clashes, or other defects, that make their classification a bit dubious.</p><p>On the other hand, its noted that some machine doubling closely mirrors a double die.</p><p>I&#039;m going to show a real life example, and I&#039;ve seen many others. This example shows what&#039;s currently known as &quot;machine doubling&quot; on the date, face, and eyelid. HOWEVER, it is NOT in a uniform direction. It is also not physically possible to be involved in a &quot;pivot&quot;. ...the doubling doesn&#039;t line up correctly.</p><p>Another thing is that, although doubling of the numbers may be flat, and shelf-life, there appears to be a clear sherif on the tip of the 9. Also, many other &quot;machine doubles&quot; examples show &quot;shelf-like&quot; appearance but the tips or ends of the numbers are equally raised.</p><p>Perhaps? Some &quot;machine doubling&quot; is part of the die engraving process. Anyone who has done engraving by hand can tell you that the initial process is the most difficult. Once the groove starts it becomes easier. This is not done by hand BUT vibrations could cause a wider grove initially. This would transfer a &quot;shelf- like&quot; appearance in some areas, while other areas appear to be &quot;true&quot; doubling, like the eyelid, series, and raised number ends...? This is a peculiar aspect of &quot;machine doubling&quot;.</p><p>Perhaps a loose die during engraving or other similar explanations, related to the process of &quot;double die&quot;?[ATTACH=full]930610[/ATTACH] [ATTACH=full]930611[/ATTACH] [ATTACH=full]930612[/ATTACH][/QUOTE]</p><p><br /></p>
