<p>[QUOTE=&quot;chascat, post: 3001619, member: 76792&quot;]Typical mushy strike due to lower striking pressure.&nbsp; The high relief dies were breaking after just a few strikes which proved to be very costly.&nbsp; The dies lasted a little longer under lower pressure, but were still unacceptable in high relief.&nbsp; A re-design in lower relief was necessary so in 1922 the relief was lower and there were fewer striking problems.[/QUOTE]</p><p><br /></p>
