<p>[QUOTE=&quot;silviosi, post: 25219223, member: 153002&quot;]My title it is the question, I present here the two type of the new era coins of the single squezee which start in 1999. What it is your oppinion on this?</p><p><b><br /></b></p><p><b>Class 9 manifests during a single hubbing</b> and can be located centrally or almost throughout the design.</p><p><b><b>There are two types of doubling:</b></b></p><p><b><b><br /></b></b></p><p><b><b>Jolted (Type 1)</b>:</b> mimics offset doubling, and is focused in a hot zone of the central design elements. Parts of a device are replicated in the adjacent open fields. They can be marginal, offset, or even show rotation. There is a maximum spread, and a limit to how much is duplicated. Typically, there is one region on a coin’s design where almost all doubling occurs. This can be surmised by similar doubling found on coins from Denver and Philadelphia. (e.g., 2009 Lincoln cents)</p><p><br /></p><p>This type of doubling is created earlier in the hubbing, when the die can still jolt back into correct position leaving only a trace of doubling. It should be noted that doubling could be caused, at least on occasion, by the press being reset during a hubbing – there is no clear indication as to how often that occurs.</p><p><br /></p><p>Decisive examples include: 2015P 25c NE DDR-004; 2009 1c FY DDR-002; and 2009D 25c DC DDR-001</p><p><br /></p><p><b><b>Roly-poly (Type 2)</b>:</b> The second type is characterized by an offset distorted extra thickness that is roly-poly in appearance. Doubling can manifest over a larger section of the die, including the periphery. Doubling is typically stronger centrally and weakens toward the edge of the design. The doubling is related to type 1, with horizontal play between the hub and die, but the point of contact seems unceasing, and instead of a jolt, it rolls under pressure extruding the design as the tilt stabilizes. On some examples, there is a wobble, accounting for notched corners and separation lines.</p><p><br /></p><p>This type of doubling can be secluded to a small area or can be widespread. The doubling is unlike class 4 with milder separation lines, soft corner notching and a roly-poly extra thickness. It is unlike class 6, in that the distortion is offset, and does not distort toward the edge.</p><p><br /></p><p>Key examples include: 2006 1c DDO-003; 2015 1c DDO-001; 2012P $1 BH DDO-001</p><p><br /></p><p>Silvio[/QUOTE]</p><p><br /></p>
