<p>[QUOTE=&quot;cpm9ball, post: 2866938, member: 24633&quot;]The use of the term <b>shelf doubling</b> is incorrect. <b>Flat and shelf-like</b> is a descriptive of machine doubling.</p><p><br /></p><p>The Indian&#039;s nose looks like it took a hit.</p><p><br /></p><p>True hub doubling is created on the die, itself, during the production of the die.</p><p>Machine doubling is the result of the die being loose and vibrating rapidly, back and forth, as the coin is being struck. In both cases, there is no way of knowing how many coins are produced, so rarity between the two is a non-issue. What is important to remember is that when hub doubling alters the (intended) design of the die, a new variety is created.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
