I believe a 1964 DDR

I could not match this with any photo s I could find. Wexler lists 116 different DDR's for this date but only has pics for a few of them.

The flat, shelf-like appearance is characteristic of machine doubling. That is not hub doubling.

 

It's not that flat. Similar to many other ddr's for that year.
Like this one

 

Sorry, looks like MD to me.

 

flat and shelf-like

 

Machine doubling!

MD

 

I have used this as a guide and read http://www.error-ref.com to study why and how it occurs, but I still get confused. Some coins I find 'Look' like the hub doubling, but keep being MD.

 

What would you call this on this 1975 D ?

 

100% machine doubling (also known as strike doubling).

 

HUGE difference between these pics and the coin in the OP.

In these pics, notice the die wear on the "secondary" image? That proves that the doubling is part of the die itself. There are also split serifs (most prominently, look at the bottom of the C and the middle bar of the E - they are complete secondary images). On the image in the OP, the appearance is flat (not part of the die). The strike doubling also shows no split serifs (that is, there is no "separation" of the images, which is a key characteristic of hub doubling).

 

you are correct. I was wrong.
Thanks to you all

 

No, its not that flat but typical machine doubling none the less.

 

I just love the effort you (presumably) put into this illustration as it precisely defines machine doubling.

 

I found another one an hour later. This one looks more promising, too bad about the damage.

 

He copied and pasted from a website. I've seen the drawing many times.

 

I got it from THIS forum under the top posts about doubled dies. I've seen it referred to many times in threads. So, it's not correct? No wonder I get confusing replays on what is or isn't DD.

 

Of course it's correct

 

here are some images from Wexler's site (for educational purposes) pictures 1, 3,5 are doubled dies...2,4, and 6 are MD. notice the difference?

Of course thank you. This one is the first real DDR I've found. Have you found any?
