<p>[QUOTE=&quot;robinjojo, post: 24496270, member: 110226&quot;]Chopmarks are punched into the coin.&nbsp; They are part of a practice that goes back thousands of years, as a main method of verifying that a coin meets certain weight and/or fineness standards.&nbsp; The slight ridges along the symbol are caused by metal being slightly displaced by the striking.&nbsp; These chopmarks were administered to coins without any heating; the merchants, traders and bankers had better things to do with their time no doubt.&nbsp; </p><p><br /></p><p>I think the &quot;raised&quot; impression might be caused by thinking that the dark lines are above the surface of the coin, when in fact they are depressions.&nbsp; I&#039;ve experienced that trick of perception sometimes when I look a coins that have strong light and dark contrast and it often takes me time to readjust.&nbsp; If you look at the enlargement of the symbol you can see some tiny deposits at the bottom of the left arm, do doubt due to the coin spending a very long time in water and buried in mud.[/QUOTE]</p><p><br /></p>
