Is This A 1972 D DDR ?

While the devices that are affected look wider, it is not a doubled die. Why? Because nothing is doubled from the hub. The die that struck your coin was normal. But why are the devices wider/weaker? Not from a doubled die. But two thing can happen to cause this. If the weight is slightly lower the metal it needs for a full strike will be reduced. Thus leaving the devices weak and looking wider.


Note the overlay where the weakness occurs. That is the same area your coin is affected. So the weight might be slightly less. Because so much of the metal is moved on the bust, that area can be weaker of the full weight is not there. If the full weight is there, there is another thing can alter the strike on that area. That is a Grease Fill on that area.the grease in the die will prevent the devices to form normally.

Note the differences on this image. Can you see the tops of the devices filled out next to the rim? That is what it will like if the weight/strike was not correct. But note on the lower image of the struck though grease. The weight will be normal for this one. The devices were prevented from forming on that area, because of the Grease Fill. Note the tops of the devices are also affected, just like your coin. So Using this information, your coin is probably a Struck Through Grease issue, rather than s reduced weight issue. I took you through the full steps in figuring this out, so in the future, when you see this, you will know what it is. Rather than just giving you the answer, I gave you the ability to figure this out for future reference. A student can know the answer and recite it. A teacher helps the student how to determine the answer. That is why I go so deep into the subject. To help the students to someday, be a teacher. Thanks for the privilege of helping you. (I want you to see what I see on your coin)

CoopHome: How can you tell the difference between strike weakness/grease fill on the Memorial reverses? (You mean there can be two causes?) How to tell the differences?
