Photo quality is everything. These photos have to befocused, sharp and not have a lot of glare.
Doubled dies are working dies that had multiple impressions on that working die of the coin design. So. Where the attributers show the doubling, is where it should be. Since these double impressions on the working dies are made of steel, the areas don't move.
if the area is lower,, shelf or step like suspect worthless doubling.suspect it more if it is not listed on varietyvista, coppercoins or doubleddie.comLast edited by MintErrors; 05-16-2023, 09:48 PM.Gary Kozera

hey, you are not alone in this. Many people have the same issue when it comes to doubled dies vs. Machine doubling. When you find one, hopefully you have that Aha! Moment.
Understand how these working dies were made prior to 1996 is crucial. The working die blanks were set into a high tonnage press. They made one impression of the die. They did not know if all of the devices (features) of the coin pattern transferred successfully. They would have to pull the die out, examine the working die to see if it had enough of the transfer. If not, they attempted to put that die in exactly like it was. Then they would make another impression, to hopefully transfer everything over.
It's important to note that these impressions are sunk, or incused into the die, so they are risen on the coin itself. They use the same pressure on each hubbing, or impression of that working die.
now, once they placed working die back into the press, and that if the working die was off just a bit whether off to the right, left, up or down just a bit, a doubled die was born.- Doubled dies should have the doubling at or near the same height.
- If the access was off enough, you may have split serifs on the letters.
- You may have those cookie cutter style lines, which show up when one impression is on top of another.
I have a few educational posts in my signature below, because these topics are quite common.
I suggest looking at this article, especially the doubled die Kennedy at the end. Hope it helps.

A photo, or two or three or more is worth a thousand words. Here is something to relate to. This is a 1964 Kennedy Half Dollar, FS-101.

IMG_1910.jpeg IMG_1909.jpeg That’s funny because I posted this 1964 Kennedy a few weeks ago and didn’t get any responses but was thinking this was machine doubling. Now I’m quite sure it is

In my opinion,unless you modified the location of the words IGWT, to fit in a single photo...this isn't a 1964 half. It might be photos from a 1964 quarter ?
On a 1964 Kennedy half dollar, IGWT goes across the entire coin, one one "line".
