<p>[QUOTE=&quot;Conder101, post: 1602818, member: 66&quot;]There are several different types of hub doubling.&nbsp; Rotational hub doubling as is seen on the 1955 and 1972 DDO cents is the type that most people think of and it does create a doubled image all over.&nbsp; But the other types can create doubling that is only present in some areas and not others.&nbsp; One case could be distorted hub doubling where the die when annealed between hubbings does not expand and shrink evenly so part of the image is not in the same place as it was in the previous hubbing.&nbsp; That can create doubling in just one part of the design and not others.</p><p><br /></p><p>If your coin is showing the same doubling on the mintmark as on other features then it is most likely NOT hub doubling.&nbsp; In 1969 the mintmark was not part of the hub and so something that doubled the image in the die would NOT be able to double the mint mark as well.[/QUOTE]</p><p><br /></p>
