<p>[QUOTE=&quot;Severus Alexander, post: 6694790, member: 84744&quot;]I wrote about this issue in <a href="https://www.cointalk.com/threads/severus-alexander-222-235-ad.373047/#post-5387574" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/threads/severus-alexander-222-235-ad.373047/#post-5387574">another post</a> back in January.&nbsp; What I wrote is just so great I will repeat it here. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" /></p><p><br /></p><p>-----</p><p><br /></p><p><b>How to tell the difference between a light sestertius and a heavy As?</b></p><p>Obviously the radiate crown allows us to identify the dupondii. For AE As vs. sestertius, the die diameter should make it pretty clear. At least for SA (and I suspect the surrounding reigns):</p><p><br /></p><blockquote><p><b>As die diameter: 23.5-25mm</b></p><p><b>Sestertius die diameter: 28-30mm</b></p></blockquote><p>*Note that this is the diameter of the <i>die</i> not the diameter of the coin! The die diameter is measured from the very outside of the circle/dots/denticles on the edge of the die.</p><p><br /></p><p>With sestertii that are a bit short on flan, you have to guesstimate how large the die is, but it&#039;s usually possible to do this within the required range of tolerance. You can usually tell where the edge of the letters will be, and often some of the circle/dotted circle is visible too. Since there&#039;s quite a gap between the two die sizes it&#039;s pretty hard to get it wrong.</p><p><br /></p><p>Examples:</p><p><br /></p><p><img src="https://www.cointalk.com/attachments/screen-shot-2021-01-07-at-2-59-55-pm-jpg.1231323/" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>This coin is 27mm and 16.05g, but is obviously seriously short on flan. The die diameter is at least 28mm, so it&#039;s a sestertius. (It was incorrectly labeled an As by the seller.)</p><p><br /></p><p><img src="https://www.cointalk.com/attachments/screen-shot-2021-01-07-at-3-05-43-pm-jpg.1231330/" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>This coin is 29mm(!) and 15.32g, but the die diameter is only 24.5mm. Definitely an AE As.</p><p><br /></p><p>In general I don&#039;t think we pay enough attention to die diameter!</p><p><br /></p><p>------</p><p><br /></p><p>In that connection, I love your chunky Annona PROVIDENTIA As, [USER=99554]@Ocatarinetabellatchitchix[/USER]!![/QUOTE]</p><p><br /></p>
