<p>[QUOTE=&quot;Conder101, post: 1801916, member: 66&quot;]That&#039;s a very good question, and I have to admit I don&#039;t know.&nbsp; In order to be perfectly round the coin would have to be struck in a collar.&nbsp; (key word is &quot;perfectly&quot;) The chinese cash coins could come close as their molds could be perfectly round, but you would have the casting spruce or possible irregularities from where it is ground off.&nbsp; Perfectly round planchets could be made and used for hand striking or coins struck without a close collar but due to irregular expansion during the strike these would not be perfectly round either.</p><p><br /></p><p>So the real question is which country was the first one to use a close collar for striking?&nbsp; I know they had it in Great Britian for the token coinages in the 1780&#039;s, but I don&#039;t know if anyone else had it earlier. (The US didn&#039;t have it til 1828)[/QUOTE]</p><p><br /></p>
