<p>[QUOTE=&quot;Guy Ferguson, post: 3616052, member: 105326&quot;]I have the same problem knowing if a coin is DD or not. I scan my coins at a high resolution and sometimes I think I have doubling and I think it&#039;s the light from the scanner causing shadows that look like doubling. What I have done is turn the coin 180% and re-scan it and if it was shadows from light, the doubling will either be gone or it will make the doubling in the opposite direction. I wish I knew for sure what I was doing.[/QUOTE]</p><p><br /></p>
