You just have to love the single strike doubling's

 

The 1995 ddo_001 Lincoln was produced by a single squeeze hub method. Many others as well.

 

That's helpful information how about some photos to go along with it.

 

The pictures posted are machine (or shelf) doubling.

 

Talking to a master technician who has refurbishes various types the United States mint presses. When it comes to the single strike doubling there are a variety of failures that could occur.
No matter what kind of failure caused this doubling one thing is sure it is a single strike doubling occurrence. USMC60

 

Another thing I find interesting is the first photo. Take a close look at the Fort lettering.
The top of the lettering is raised the bottom of the lettering is lower, now keep in mind all these letters are embedded in the planchet on a single strike.

One thing I would like to see is a computer animation of this failure. I'm still trying to figure out how it can happen on a single strike and at the speed that it happens at.

Looks to be MD or even Die Deterioration Doubling to me. Very common but still nice to look at. Put em in 2x2's and use em for learning purposes.

 

Doubleddie.com shows great photos of all the known doubled dies. Your coin exhibits What I believe to be deterioration doubling.

 

I believe single squeeze hubbing was not introduced until after 1995.

 

Your rite not till 1997

 

Just wanted to add this other Fort doubling that I came across.
