<p>[QUOTE="mikediamond, post: 2236516, member: 1859"]This is not grease-mold doubling. The extra hairline above Lincoln's head is an example of split plating doubling. The doubling of the 9 and below the bust may represent plating disturbance doubling, where the plating lifts up after it's subjected to the tensile stresses of the strike. It's the numismatic equivalent of an Indian burn bad enough to create a blister.[/QUOTE]</p><p><br /></p>
