What to look for on these? spread of the devices. don't look at the outside edges. that is where you will find Machine Doubling or excessive die wear. so always look for the spread of the devices. the notching is cause on these by the spread of the devices. Click on the link below to see the full discussion of this subject. https://goccf.com/t/443697#3826536 How to identify a 1969-S doubled die DDO-001 and not be fooled by Machine Doubling? Why does Machine Doubling never make a coin a doubled die? Machine Doubling is a post strike event. a doubled die comes from a die that has hub doubling on it. Machine Doubling is nor raised. a doubled die raised as it is part of the hub doubling on the die. Thus without the area being raised, it is not a doubled die. doubled dies are caused by a doubled die. Machine Doubling is caused by a loose machine.

coop Bedrock of the Community United States 62064 Posts	Posted 04/15/2023 2:17 pm How can you tell the difference between Machine Doubling and hub doubling or die wear? CoopHome: What areas on the Shield cents can show hub doubling on the design? How is Machine Doubling different on incuse devices? hub doubling enlarges/reduces the center areas of the design on the single squeeze dies. seeing this all of the same coin helps us see the facts on this hub doubling. Machine Doubling dies the exact opposite on the struck coins. Machine Doubling is caused by the machine. doubled dies are created on the die. thus only a doubled die coin will strike a doubled die coin. Machine Doubling can happen on a doubled die, but it is never part of the doubled die, just alters the coins devices post strike. so knowing this information will help train your eyes for the differences. raised doubled dies will enlarged on the center of the coins devices. Incuse doubled die devices will be enlarged Machine doubling reduces the raised devices on one side of the devices. die wear will always show towards the rim direction. On incuse devices, Machine Doubling will enlarge one side of the devices. So Machine Doubling and die wear act oppositely on the coins devices, than what happens on a doubled die. Hard to remember, but always remember the areas affected. Doubled dies are affected on the centers of the coins devices. Machine Doubling affects the outer edges of devices. Why? Again because the machine causes the affecting of the outer edges of the devices. See the differences? Doubled dies are always affected on the centers of the devices. (enlarging/reducing) Die wear is always towards the direction of the closest rims. Hope this helps with this discussion.

coop Bedrock of the Community United States 62064 Posts	Posted 04/16/2023 2:59 pm All You ever wanted to know about RPMs/Mintmarks CoopHome: What is a RPM? Are there different types of RPMs? Will they always be enlarged? Can mintmarks be smaller than a normal mintmark? looking for the punches on a mintmark will show you if it is a RPM or not. it should be enlarged larger than a normal mintmark. these can also happen with two different mintmarks as well, making these an over mintmark: Inverted mintmarks: The mintmark is enlarged, but no sign of multiple punches, then it is not a RPM: The punching enlarged the mintmark, but no evidence of separate punches.

coop Bedrock of the Community United States 62064 Posts	Posted 04/20/2023 1:58 pm Post 1999 quarter doubled dies? How are they different than earlier doubled dies on quarters? Raised and incuse devices differences on the single squeeze dies. different locations for the doubled dies and Machine Doubling rules on the newer coins with the single squeeze die coins. how to tell the differences? Click on the link below to see the full discussion of this subject. https://goccf.com/t/444336#3833123 Sometimes you need to study a bit harder to grasp the differences. When you figured this out, then you will start finding doubled dies easier on the the single squeeze dies. You maybe looking in the wrong areas and some devices will not have a doubled die as they design transfers don't happen on some designs. So save your eyes. Know what to look for the that design before you start looking. So look at the listings to see what you could be missing now. Then your eye will be trained to look in the correct areas and what to look for. Don't worry about the past searches, now your eyes will spot it the next time around when searching. Looking in the wrong areas you might be distracted by Machine Doubling and die wear. Know before looking, then you will find what you are looking for. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 05/02/2023 10:51 am Presidential Doubled dies. What to look for on this series? What to look for on the President Dollars for die varieties? Distortion and enlarging of the devices on the central areas of the design. Machine Doubling and Die wear ( DDD) is not a doubled die. Click on the link below to see the full discussion of this subject. https://goccf.com/t/445050#3839750 How to detect on zinc plated coins if they are altered post strike or if they are struck that way? First clue, note the outer edge of the devices? Note they gray color there? That is where the zinc is showing, where the plating was removed on this coin post strike. This coin was altered. So all the devices that are altered, are flatten and distorted post strike. Just a spender. Not a doubled die, not a Struck Through Grease issue. The clue again, if the coin had gray showing, it was there when it was struck. So this coin was altered post strike. With the gray color present, some of the plating was removed post strike.

coop Bedrock of the Community United States 62064 Posts	Posted 05/17/2023 12:52 pm Why are some field devices altered on proof coins? CoopHome: What causes the fields to show distortion on some of the proof coins? Machine Doubling on the first strike. the Machine Doubling was present and the second strike flattened the affected devices. (or in some cases, enhances even more on some strikes. most are normal, but the MD is seen on the first or second strikes on proof coins on the fields.

coop Bedrock of the Community United States 62064 Posts	Posted 05/21/2023 2:54 pm What causes and affects do die cracks have on coins? Why are die crack common on some designs? over usage of dies and come designs will also tend to have these from the die clash events. the Memorial cents are often affected. possibly because of the 4 corners on the outline of the die. thus they crack more often on this design. The die cracks will be raised on the coin because they are incuse on the die.

coop Bedrock of the Community United States 62064 Posts	Posted 05/22/2023 12:08 pm What happens to damaged coins? CoopHome: Damaged coins If it is a die issue on a struck coin, it will be raised. If it is pressed into the coin, then it is damage. A die chip that is missing part of the design will be raised above the surface of the coin. A die crack will also be raised above the surface of the coin. A coin scratch will be incuse, below the surface of the normal coins design. Incuse devices on a coin will be below the surface of the coin. If there is damage on the surface of the incuse devices, they will also be slightly below the surface of the coin. Damage to a coin is below the surface of the normal coin more or less, depending on the train wreck it went through. Damage is never a plus for a coin, just making the coin into a face value only coin. When these coins get back to the banks, they will be set aside and returned to the mint to be cancelled and scrapped. If the coin can still be used, it is left in circulation. Click on the link below to see the full discussion of this subject. https://goccf.com/t/446041#3850239 Die polishing reduces the size. How? The die has the opposite appearance than the coin. What? Everything raised on the coins will show on the die as deeper into the dies. Besides being mirrored the fields are the outside edge of the die. The devices are deeper into the die. The taller the device is on the coin, the deeper the devices will be into the die. Note the outer edge of the die has a gutter? That is what helps for the rim on the coins outer edge of the design, protecting the devices on the coin. When a die is polished, what is affected first? The fields. These are often altered first on the die. The later die wear will affect the incuse devices on the die. But when a die is polished, the devices bases are the widest/tallest parts of the design. When the polishing happens, the bases of the devices will be reduced in size, making the devices shorter and thinner as the die gets the fields polished more and more times. Why are the devices tapered? If they weren't the coins would strike to the dies post strike. So the tapering of the coins prevents them from being stuck on to the dies. What is why the devices will be reduced in size as the fields are polished away. On a doubled die, the devices are enlarged on the die because of the hub creation on the die. Thus looking for enlarged devices is what to look for. Reduced devices are just a normal die that was over polished. Hope this helps? CoopHome: Why are some devices reduced in size on the coins?
