<p>[QUOTE=&quot;desertgem, post: 1565818, member: 15199&quot;]Normally coins for circulation are struck by the dies only once. Proof or special surface coins are generally struck 2 or more times.</p><p><br /></p><p style="text-align: left"><span style="color: #000000"><br /></span></p> <p style="text-align: left"><span style="color: #000000">No, the doubled dies (before single squeeze die production), occurred when the working die was pressed ( squeezed) once by the working hubbing die, and then after removing the working die from the press and heating to soften it , it was pressed again with the working hub. If the working die/working hub did not line up exactly, a second overlapping image ( usually as strong ( height)&nbsp; an image as the first ) was produced. Thus the working die had a doubled inverse image and when it struck the blank , it produced a doubled die coin. Since the obverse die and the reverse die were produced separately, one or the other could be doubled irrespective of the other side. </span></p> <p style="text-align: left"><span style="color: #000000"><br /></span></p> <p style="text-align: left"><span style="color: #000000">Now if the working die became loosened in its holder, it could move during the time of pressing a coin, this is Machine Doubling, and not a doubled die. Sometimes a coin is not ejected perfectly, it might be struck a second time, with the same dies and the result can have many different appearances, reasons, and names.</span></p> <p style="text-align: left"><span style="color: #000000"><br /></span></p> <p style="text-align: left"><span style="color: #000000">Jim</span></p> <p style="text-align: left"><span style="color: #000000"><br /></span></p><p>[/QUOTE]</p><p><br /></p>
