2011 Nickle / Strike double?

[CopperFinger]

Hi All, found this nickle with the other one the other nite thought it looked interesting. It looks like you could pry thhe letters off with a knife or something..Thanks...

Good example of machine doubling. A few collect examples like this and no problem with that as long as they know it's not a doubled die and not related.

What indications are on the coin that tell you that it is machine doubling? Just wondering so I know more of how to tell the difference between machine doubling and a actual double die.

The flatness of the doubling and the fact that it looks like you can pry it off with a knife, doubled dies don't look like that.

This coin is a great example of machine doubling. (there are more subtle examples also).
j_a, if you study it and look closely at the secondary markings you will pick up on the telltale signs .
With machine/mechanical doubling the coin slides or moves slightly as the die strikes the surface, making the devices look like they have moved or has slid from the original contact point. It can be significant and affect large areas or be contained to a small area (or even singular devise).
With doubled dies, the doubling occurs on the die when it is created. It then transfers that doubled design onto the coin upon striking the planchet.

I see what yall are saying awesome thank you

j_a,

What I look for to determine if it is machine doubling:

1. Is the secondary image flat?
You cannot always tell this one. But, when compared to true doubling, it is distinct.
2. Is the doubling in more than one direction?
Look at the two 'O's in MONTICELLO.
3. Are any of the devices thinner than normal?
True doubling always increases the size of the device.
As Daniel stated, the die shifts slightly just as the pressure is released from the strike. The edges on the die that previously formed distinct letters, now cut sideways into those letters, shifting metal. Because this is not a strike, it thins the normal width of the lettering.
Look at the upper loop on the 'C' in MONTICELLO and compare it with the lower loop on the same 'C'.
There are other letters showing the same issue.
4. Does notching exist?
True doubling creates a second image of the device. When that device has corners, you will then see two distinct corners. Machine doubling drags the metal across the surface, so a second corner is not distinct. This is obvious with the 'T' or 'N' in MONTICELLO. If the machine doubling is large enough, it may appear to have notching.
