<p>[QUOTE=&quot;Gallienus, post: 3427171, member: 42034&quot;]Thanks very much!&nbsp; You appear to be correct.&nbsp; I googled the subject and found an article by Calgary Coin discussing the metallurgy in more detail.</p><p><br /></p><p>There seems to be a supply of older articles also stating that ancient coins were struck hot.&nbsp; I think it should be possible to look at the metal grain sizes with an electron microscope and determine definitively.</p><p><br /></p><p>Nonetheless I&#039;ll use this thesis, that ancient coins were struck cold as it seems that the evidence points towards it.&nbsp; In less than a month I&#039;ll be giving a talk on Ancient History as Shown by Coins to 10 6th grade classes and I have a slide on how they were made but I&#039;ll include the new findings.</p><p><br /></p><p>Your avatar, however, was not struck cold but made from hot (molten) bronze.[/QUOTE]</p><p><br /></p>
