<p>[QUOTE=&quot;acanthite, post: 868816, member: 6647&quot;]Nice coins, the theory on favored use of the cracked die is interesting.</p><p>&nbsp;</p><p>I do work with overdates, but from a much later era.&nbsp; I have seen some examples that illustrate what your Ptolemy tetradrachm appears to show, ie. a reverse overdate.&nbsp; I see two possibilities.&nbsp; First, that the engraver prepared a die for use only after the date became valid, but circumstances forced reworking of the die for use before it was meant for service.&nbsp; Your coin makes me wonder about that, since the gamma is so much bolder than the lambda.&nbsp; Second, the cases I see, in which a die is used into the following year and has to be forward dated, but the engraver or date puncher does not apply enough force to sink the new digit deeper than the preexisting digit.&nbsp; Also, supposing that the die worker attempts to add material to the die to plug up the old digit while tooling it, at some point in the die life that material can fall out, gradually or suddenly betraying the old image.&nbsp; </p><p>&nbsp;</p><p>In any case that Egyptian example is great eye candy for variety collectors, thanks for posting.[/QUOTE]</p><p><br /></p>
