1969 S Quarter DDR (From Proof Set)

Looks like normal design to me.

1969-S has only one DDO and 5 (five) RPM's. Your coin is really normal proof strike. What you see is not DDR it is the results of the 3 to 4 strikes for proof introduced in 1969

This is called "Flat Field" devices. They are seen only on proof coins. Why?


Because the proof coins are struck twice. So any Machine Doubling on the first strike of the coin happens, the second strike will flatten it. This happens on regular dies and doubled dies.

Often on Variety Vista, you will see this affect, but it has nothing to do with the hub doubling of the doubled die. So always check the Description box to see what is hub doubling.

They don't point out Flat Field doubling as it is a striking issue, not a die issue. Why does that make a difference? Because the strikes cause this, not a doubled die issue on the dies. So it can happen on either types of dies, and can been different from strike to strike. So it is not a doubled die.
That is what you are seeing on your coin. Not as strong. The Flat Field doubling will be flat (thus the name), but a doubled die will be raised on the coins devices enlarging the devices. The FFD is not a die issue, but a striking issue.

CoopHome: What is flat field doubling, and why it this not a doubled die? FFD happens during the strike, and not a die issue, but machine movement issue during the strikes (proof coins are struck twice or more on some designs)

On the fields is where the flat field doubling is seen. On the tops of the design, would where you would expect to find spread. So create a set of images of a normal proof coin for that year/proof and make images to match of the same size. Looking too close at something is not always a good thing. It just make it look like something, when it is just too close to look. So include on this outer devices, of at least 4 or more devices in a row to see what is really going on with that area. Then compare the outer sizes of the devices to see, if they are enlarged or normal in size. The affected area could be a high bounce Machine Doubling affect on the tops of the devices. On the image of the Stars, it looks like Machine Doubling on that device. But seeing the images side by side will show if they are enlarged or not. So seeing even full words, sometimes helps to see if it is really enlarged with hub doubling, or contact or high bounce MD. Take the images with the same rotation on both sets of images to compare with. Then make the side by sides to see what is seen then. If no spread, then it is not a doubled die. If no spread in over al size, but an area is reduced in size, it could be contact or high bounce damage on the tops of the devices. But the closer the line is in the centers of the devices, you would expect the devices to be a doubled die if they are really showing spread. Keep us posted on what you find. Post images if you are not able to make them into side by sides. You can get them close on the forum. Post one image with the area below the devices crop close at the bottom. (the normal image) and the image in question, crop the image tops closer. The they will be close enough to be seen on the screen closer. The Max I use for width is 1200 pixels. (Sometimes that is reduced on the screen) Look forward to your results.
