<p>[QUOTE=&quot;HenryKnox, post: 2753349, member: 87725&quot;]From Wexler:</p><p><br /></p><blockquote><p><i>&quot;In the Wexler Die Variety Files we define “doubled die” doubling as doubling produced on hubs or dies as a result of a misalignment of the images on the hub and die at some point during the hubbing process.&nbsp; A more accurate term would be “hubbing doubling,” but the term “doubled die” is clearly fixed in our culture and here to stay.&nbsp; The misalignment of the design images may have been when the master hub was squeezing an image onto a master die, when a master die was squeezing an image onto a working hub, or when a working hub was squeezing an image onto a working die.&nbsp; Just where the doubling occurs in this sequence will dictate how common the doubling will be, and that will affect the subsequent values for the doubled coins that are ultimately produced.&nbsp; Doubling can also occur in the process of transferring the design from the galvano to the master hub.&nbsp; Links are provided here to get more details on the doubled master hubs, the doubled master dies, and the doubled working hubs.&quot;</i></p></blockquote><p><br /></p><p>According to this definition, doubled dies result from: a) misalignment; or b) engraving defect.</p><p><br /></p><p>What I am attempting to establish, is that die cracks, like doubled dies, are the result of a defect with the die or the die impression.[/QUOTE]</p><p><br /></p>
