<p>[QUOTE=&quot;paddyman98, post: 3451181, member: 44615&quot;]I think you mean Die Rotation. The hub is not what is used to strike a coin.. a Die is what is used.</p><p><br /></p><p>Definition - A <b>hub</b> is a positive, or relief (raised) image of the coin&#039;s design that has been impressed into a steel shaft during the process of creating the tools that are required for making coins. The original coin image is actually a plaster sculpture about 8 to 12 inches in diameter, from which a <i>Master Hub</i> is created using a special process that reduces the image to the actual size of the coin. This Master Hub, which bears a relief image of the coin design, is then copied on to a number of <i>Master Dies</i> (which bear the negative, incuse or sunken image of the coin).[/QUOTE]</p><p><br /></p>
