<p>[QUOTE="Conder101, post: 2941695, member: 66"]The problem showing pivoted hub doubling is that the pivot point can be anywhere on the coin, or even off of it. The images show the pivot point on the rim at 3:00, but if it was say at 6:00 the areas of doubling would be quite different. The 1995 DDO cent is an example of pivoted hub doubling with the pivot point located close to the date. On pivoted hub doubling the doubling will be greatest 180 degrees across from the pivot point. If the pivot point is not on the rim there will be doubling on both sides of the pivot, the greatest at 180 degrees and a much lesser behind it. The closer the pivot point get to the center of the coin the greater the doubling will be behind it. Rotated hub doubling is actually just a special case of pivoted hub doubling where the pivot point is at the center of the die.[/QUOTE]</p><p><br /></p>
