Machine doubling. Worth face value. Edit: didn't read the full title at first, but as John said, both Machine Doubling and Mechanical Doubling refer to the same phenomenon, which is not of any value. Doubled dies are what you're looking for, which this is not.

Nothing to add except that those are way above average close-up pictures @sav. Well done.

Yes, Ive noticed Double Dies are hard to come by and with me being a novice collector when I come across MDs it's exciting even though they are worthless, lol.

I agree with Makescents about a combination of Die Deterioration above RICA and MD at the 9.

The images are showing two different things. Machine Doubling on the date. Note the die striation lines on the left side of the '9'? That is the edge of the die, creating these lines in a sliding motion. On the first image, that is die wear. The die flow lines are causing the flow lines to the rim. If a device is preventing the die flow lines, then they are not present on the area between the devices and the rim. If it just part of the aging process. Neither are a premium for the coin. But the premium is knowing what happen to cause them. When you see this again searching, then you can move on to the next coin. No premium for this, just knowledge of know what it is.

coop Thank you for the valuable info. I've only been collecting for a few years, I have a 2009 A $100 note - LH 00000003 A I found here in Phoenix but my coin collection will have to be thoroughly gone through because what I thought were DDs are probably not. Time to break out the cheap Amazon USB microscope, lol.

Quote:These are two different coins, I've been told Machine Doubling and Mechanical Doubling. What's the difference? Improper language and denomination. Who come first with? No idea, but not an specialist of the field of the minting processes. In fact is referrer to the same phenomena which the best describe will be Mechanical Doubling. Why? because those things occur as result of an action (Mechanical). Machine Doubling is really wrong to say, because a machine is a hole gear and is compose by many different parts in order to have the mechanical action. Many terms are results of x person who give that name without any education on. Those terms are use from many years, and probably will rest.
