<p>[QUOTE=&quot;dougsmit, post: 911367, member: 19463&quot;]True.&nbsp; Most people will give the min and max diameters of such coins if they are over 2mm difference but things more round are approximations.&nbsp; Many ancient coins are of uncertainly named denominations and will be denoted by metal an size so AE18 is a bronze coin of about 18mm diameter.&nbsp; An AE 18x22 would be a very oval coin.&nbsp; If you have an example of a coin listed in the catalog as an AE18, it is quite possible that yours will be AE 17 or AE19 or as irregular as could be since repeatability was not an important concept in many ancient civilizations and an extra strong hit by the hammerman could make a coin a bit bigger.&nbsp; Most were more concerned with weight than diameter or thickness. There are exceptions where ancient technology made very precise coins the rule but the concepts of bank rolls and stackable coins had not occurred to most of the authorities.</p><p><br /></p><p>Rule makers in ancient coins rarely follow consistent rules.&nbsp; Experts in fourth century AD Roman give little concern to how those in 5th century BC Greek wrote up their coins.&nbsp; Sometimes you will see a book that specifies that they took measurements 9-3 or some other way but someone studying a relatively unpublished specialty is quite likely to pick rules that fit that subject rather than feeling the need to follow random rules of another student.[/QUOTE]</p><p><br /></p>
