Nice find there Wayne..I did know they were still popping up ..

Nice find Wayne. Is that machine doubling on ONE CENT or is it glare?

[Wayne]

Thats just glare.

[seal006]

Way cool, wow there were so many DD for the FY cents. Is it because of the large amount of devices?

[seal006]

Will, you completely misunderstood. The reverse design on the FY cents is the most, for lack of a better term, "busy" the Lincoln cent has ever had. There are more devices, and more multi level devices, all covering a larger amount of the surface area, with less field area. Devices are what shows doubling, not fields. Thus it stands to reason that the more devices covering a wider area would show doubling more than a flat field. Add that to the fact that the relief is so shallow would make even the slightest offset much more obvious.

So, the amount of devices does not increase the number of doubled dies. It makes more doubled hubbings more visible than ever before.

Billy Crawford had a post a while ago explaining this. It has to do with the conical shape of the dies before they are struck. I cannot find the post.

I did find this thread: http://www.lincolncentresource.net/forums/showthread.php?t=5070&highlight=conical+kiss

Nice find's! I just found one of these in terrible condition. lol

I'm not sure more devices help. The obverse isn't loaded, yet we see many DDOs. The 2009 EC saw many DDRs, yet the shield design has seen fewer even though there should be nearly as much to double.

Devices that are most frequently hub doubled during a single squeeze hubbing are centralized, and I agree with Crawford on his hot zone on a die face. Doubling is typically stronger in the center and gets weaker toward the periphery. There are exceptions of course.

It seems you need a device, or a raised part of the design on the hub, adjacent to a field or a lower part of the design. Being most modern doubled dies impact the same areas, it may also be tied into some quirk of the design and how the hub sits on the conical die face. We see RTY of LIBERTY and the first the digits of the date - diagonal from one another. But the 2009s are not often diagonal like this, they are concentrated in one region of each design. If it were just because of the sheer number of devices, I would expect to see DDRs on many other areas on the 2009 FYs, but we don't.

But really it would be hard to have an objected answer built on stats of recent designs by counting devices and looking at the listing numbers to see if there is a correlation between them, or not. So my response and any other is subjective. Though...I then drift over to the Roosevelt reverse which has very few DDR listings and a lot of devices.

I am babbling with the keyboard - I have more thoughts, ...but I am sick and need to go to sleep...

Nice finds, the 1DR-002 is still my favorite of all of them:
