First one is a 1983 with MD. (I think) Strange how it is on one side of the letters "S" "A" "M" but then on the other side of the "C &A" with only the top affected on "E - I".

This is a 2001 and it looks like the die moved upwards when struck. It is in all of the letters, just hard to tell in the picture.

Am I correct or would this be post mint?

the "E" in WE looks like more than/different than Machine Doubling or post mint damage to me.

Train,

On the 2001, is there zinc showing thru anywhere around the devises?

Regarding the 1983,I have seen a ton of strange MD coins but can't remember one like this. The MD on the "A"s in America, is almost 180 degrees out from each other. Trying to understand how this happened. Was the die just bouncing all over the place?

The Machine Doubling on these coins doesn't change direction, the letters do. All the doubling seems to come from the northeast going southwest.

There is no zinc showing on either coin. I wish I had a better microscope. It hurts my eyes to look at that "E" though.

Umm, both are Machine Doubling. That's what "die shift" is. Chatter, slide, re-bounce, Strike Doubling, Machine Doubling. Call it what you want, but in the end it's all the same thing.

I didn't really expect it to be anything else, it was just kinda neat and was looking for confirmation. I have actually found a few coins with the die shift thing but usually on the date and for some reason it is not all the numbers. This time it was the whole phrase. Although not worth anything, I have a "fun" box these will go in. I don't know why I save these things, it is just hard to throw back an anomaly.

Thanks for all the replies, you guys are great. This is by far the best forum I have ever been a member of for any topic.

Take care all,
Tim

Thx, Chuck,

Morgan, what I was trying to say, and poorly, is on the the first "A" in America, the die had to bounce more or less left after the initial strike to create the doubling. On the last "A" the bounce had to be to the right after the initial strike. So, I guess the die first bounced left then bounced again and went right. Does that make any better sense?

I'm tryin

Jim

Jim, it is possible to have Machine Doubling in more then one direction with multiple bounces. That is not the case with this coin. As the picture is now, the first A points almost north with the doubling on top and right side. Straighten the whole coin and the top C & 2nd A are almost facing due east. Thus the doubling on the left side of letters. Hope this helps.

Looking closer, there is more... The "N and T" of cent and the side of the memorial, greatest by the initials, but the initials themselves are unaffected.

Morgan,

Not being stubborn but I still do not see it.

If you align the picture so as to put the first "A" at 12:00, it seems that the die bounce would be slightly down toward 6:00 with a slight die rotation CC. This would allow for the doubling at the top of the A and not at the bottom. Now, with the same alignment, the downward motion would move the die into the second "A" on the side struck, but the CC rotation would have caused the doubling to be toward the bottom or base of the A and not at the top.

Or am I just going to see this one.

Anyway, thx for trying.
Jim

My fault Jim, I should have done this to start with. I'm not sure which die is placed upsidedown, but for the sake of the issue here, lets say the reverse is in the proper alignment.

If the bounce goes upward in a northeast direction the right side of the letters will show the Machine Doubling. As the legend curves around the rim they are no longer straight up and down. The C and A are almost facing downward thus exposing the left side or back of lettering to the bounce.

I think the point here is that the "slide" all happened in one cardinal direction (as it would relate to a compass), and if you are comparing letters along a curve, you have to adjust the position of the slide for the position along the curve. It's Machine Doubling.

The reason the designers initials are not affected is because they are beveled better, shallower, and would more easily pop out of a die than the sharp, high relief building next to the initials...so the building gets hung up in the die, the initials don't. Pretty simple.
