What is the collective opinion regarding this doubling?
Could the piece of material at 10 o'clock have caused this?
I can only hope this picture is loaded.

nothing before the http.

I did it for you. Whats the prob?

Appears to be standard mechanical (machine) doubling.

I was going to opine "strike doubling" and as I understand it is common and nothing to get excited about. But I have yet to read a good description of the phenomenon and why it is so common and not worth much!

Copy the "IMG" file instead of the "http". If you hold your pointer on the photobucket image, a box will appear with four image options. Thw lower option is the image. Click once to highlight then to "Crtl C" on the keyboard to copy then "Crtl V" to paste in the forum message. You will see the file string after coping, but the picture will show after posting the message.
Use the testing fourm to practice.

Although this type of doubling closely mimics a true doubled die, this type of doubling is far from a doubled impressions of a squeezed die hub. Most variety collectors often refer to these anomalies as Mechanical Doubling Damage or (MDD) It is also commonly called machine doubling, strike doubling, shelf doubling, ejection doubling, and chatter doubling, but they basically all mean the same thing.
Coining presses are designed to withstand enormous cyclic loading and unloading but as with anything mechanical, they are bound to loosen with time or begin to vibrate. Composed of threaded nuts, bolts, plates, hydraulic pistons, cams. levers and an assortment of other hardware, they are bound to shake themselves loose. It does not take much to misalign a letter or device on a coin .0005 of an inch.
Most doubling is caused by loose dies that twist slightly after coming into contact with the planchet, causing the die to slightly drag on the surface of the flowing metal, which produces a flat, shelf-like doubled appearance. Solidifying instantly, the result is this layer just slightly off center from the initial strike, which at first glance mimics a re-occurring doubled die strike. I say re-occurring, because not every coin in succession appears machined doubled as in a true doubled die. The machine doubling is random in nature and usually indicates that an adjustment on the press is in order.
Since this is considered mint damage that happens all to frequently and to all denominations coined, error collectors are just not that interested in obtaining something that is inherent in the normal coining process. Sure, having a few examples of machine doubling is interesting, but none are listed nor are there any significant designations like DDO or DDR used by the hobby.
There you have it, others, please add to or correct this information.
