Keep on truckin, there are some Doubled Dies still out in the wild. You just have to put on a deerstalker cap, puck up a magnifying glass and sleuth.
I have heard and been told, "The thrill of the hunt is greater than the results" because the results wane.
This type of doubling, which is also known as strike, ejection, shelf or shift doubling, is not the result of the design on the die being doubled.
Notice that the doubled area is flat and the raised area is thinner than normal. These are the characteristics of mechanical doubling. MD isn't considered an error and adds no value. For every true doubled die, there are multitudes of MD and die deterioration doubled coins out there. If you want to look for doubled dies, you have to study the minting process and be able to tell the difference. Here is a link that does a good job of explaining true doubling vs worthless doubling. Book mark it and study it. https://www.doubleddie.com/144801.html
If you look at the 2's in the date, That is the tell of MD. A true dd most usually only goes one way. On your coin the "doubling" goes both east and west. Now in case of the famous 55 cent the DD does travel around the coin. But on the devices they are they same way. On your coin. The devices travel both ways on the same device.
awesome pictures so whatever your doing there keep doing. keep looking for that 1st DD because what your showing today is only machine doubling probably caused by die deterioration. when you get some time read up on the subject of DD and MD. once you understand the process then you will start seeing the difference. i had to read probably everything there is on the 2 varieties but i got it and you will to. good luck man
I just quickly read through this post to see some of the answers . First understand what kind of doubling is known for the year, and the areas in doubling This coin was struck from the single squeeze presses . Happy hunting everyone
