On macro images, it is best to only use one light. On full coin image some use two. But on the macro images, two light sources remove the light and shadows. It makes things hard to see if there is doubling or the lighting is creating the look of doubling. So best to use just one light source. On your coin the die that struck it was showing extreme die wear. The the die flow lines around the devices. Also there is a lot of glare on the devices. Either too much light or you need to diffuse the light. So the light will hit the devices and not drown them so all be see is white. But I see a normal coin with just a few die wear a slight Machine Doubling issues. See how light and shadows help the eye to see the raised and lowered doubling the spread has on this doubled die?

coop Bedrock of the Community United States 62064 Posts	Posted 01/20/2019 5:13 pm Question: Where do you see doubling. I see push from Machine Doubling and excessive die wear. But the image a lot better. Keep using that new setup. When you get the right coin, then you will know you have a doubled die. Something to work on is how you view a doubled die. A doubled die will show spread on the top of the devices. You are looking at the edges of the devices. On the top of the next to the rim, that is die wear/deterioration. the middle curve that is Machine Doubling. While it doesn't look flat, there was a push that made metal striation lines on that area and also on the upper loop towards the center. All I see is reduction of the device, and not an enlargement of devices. Spread will show as enlarged in size: Note how these devices are enlarged. On the center of the devices you can see spread. Note how your eye fall on the tops of the devices where the spread is present. On your coin your looking at the outside edges of the devices. All you will see there is the die wear and Machine Doubling. Look at the centers of the devices: Note the shape of the 'T's on TRUST. Now compare with your coin. Can you now see the differences? That is what you will need to see on a doubled die, the devices enlarged. Machine Doubling happens after the strike happens and most of the time is is flat looking: The difference in value between Machine Doubling and a doubled die? Machine Doubling is basically damage to the devices, so I say it is worth face value. But the coin in the first image can be as much as $200 in BU condition. So train your eyes to find what will make you a lot happier finding. MD is a common find, A doubled die is a lot harder to find. So keep on looking, they are out there.
