Hi all, this is my first post, Came across a few interesting errors and tried to take pictures as best as I could the only error I didn't manage to capture is the huge indentation that's on the coin with the dent being on the eagle and It protrudes on the late Presidents side. Any feedback on the proper terms of these errors would be appreciated.

Errors : A missing bit on the R (TRUST) Doubling on part of Dollar, Indentation

It would appear that the R in TRUST took a hit after the coin was struck. Given the photos posted, I'm not seeing doubling in DOLLAR.

Thank You ijn1944! The doubling is barely visible I have taken a few more close up shots, or could it be the lighting playing tricks on me?

That is Machine Doubling on the DOLLAR. Not a doubled die. Just machine damage on those devices after the strike. Note all the affected areas are:
1. On the outside of the devices.
2. The contour is removed from that area.
3. The devices are reduced in size. (On a doubled die, the devices would be enlarged)


DDR and Normal die with Machine Doubling:

Note how on the bottom image, what affect the hub doubling has on these devices? The MD alters the outside edge most of the time on one side of the coin. The DDR show a spread on the centers of the devices, not on the outside edges. Why? The hub misalignment creates the spread between the two locations. But Machine Doubling can also affect a doubled die just the same way that it affects the normal die. Best suggestion, When looking at coins look for the enlargement of the devices. If none os present go onto another coin. It when you start looking at the outside edges, then you find the MD. When see this, move onto another coin. Nothing worth convincing yourself at that point. These will just out at you when you find a doubled die. You know when you see one.

Which one is the DDR? Pretty obvious when you instantly see it. If you looking for a doubled die, then it probably isn't there. It will yell! Hay, look at this! You will know instantly what it is.

Which ones are yelling? Look at the centers of the devices, forget the outside edges.

Also look at the centers of closed devices:


Do you see the center of the devices affected? That should grab your eyes first.
So if you find yourself rechecking a coin over and over, guess what Machine Doubling will catch your eye. But is nothing is spotted as enlarge on a coin, move on to the next one. Don't convince yourself that something is there, when it's not. When you find a doubled die, you will know it without question.

to the CFF!

Now that you have mastered the photography end of posting (good job!), please ask more questions as you develop them. You can learn a lot by reading older postings, and if needed, there is a search box at the top left of every CFF page. Again, welcome!

Or type in CoopHome on a page. When it turns blue it will take you to a thread with a lot of links of threads and answers I've made to get answers quicker. Thousands of images on this thread links. So click on the blue link and it will take you there. There are three pages of thread links and comments. So Pages 2 & three have the most updated links.
