<p>[QUOTE=&quot;Conder101, post: 3380060, member: 66&quot;]If they used the same blanking punch for both&nbsp; I think there would be a problem.&nbsp; I think the only way to get a finished Piastre almost a mm larger in diameter than a US dollar, they would have had to have struck them on blanks without an upset rim.&nbsp; Normally the punched blank is the same diameter as the finished coin.&nbsp; It is reduced in diameter in the upsetting mill, and the the striking expand it back to the finished size.&nbsp; If you started with a blank the size of a silver dollar and then upset the rim I think you would have great problems getting it to expand to a diameter a mm larger than the finished size of the dollar coin.&nbsp; I would think you would have to use significantly higher pressure, and the dies would suffer severe wear around the periphery from the excessive metal movement.</p><p><br /></p><p>If you did use larger diameter blanks for the Piastre and upset the rims, I think they would still be large enough that they probably wouldn&#039;t fit into the dollar collars.[/QUOTE]</p><p><br /></p>
