<p>[QUOTE=&quot;desertgem, post: 830751, member: 15199&quot;]Zinc does have some stress (work) hardening capacity due to a shift in the metal crystals, but during the 1940s, many foreign countries used zinc for their minor coinage and I haven&#039;t seen or heard about much of this on them. Maybe someone that is an expert in foreign errors could comment on zinc.&nbsp; I do not know how many of these zinc coins were minted per die, so maybe it just didn&#039;t get to that point of die condition.</p><p><br /></p><p>Jim</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"><br /></span></p><p>[/QUOTE]</p><p><br /></p>
