When determining relative coordinates you have to have a scale. For the purposes of determining these coordinates I have chosen the width of the &quot;9&quot; in the date as my scale. Although I do not know the actual width it always remains consistent and equal to its width no matter what size image of a coin you are graphing. Since the actual width is unknown I have assigned it a value of 100 or in others words 100%.</p><p>[ATTACH=full]585180[/ATTACH][/QUOTE]</p><p><br /></p>
