has any one seen a coin like this? I have looked all over the place. Any suggestions on how to find out more info about this coin?
this is mechanical or strike doubling. Not to be confused with the sought-after doubled die. On true doubled dies, the secondary devices are raised to the same level as the primary devices. The fact that what you see on this coin, the stairs-like appearance of the anomaly, is a clear indication of MD. Keep it for your own reference and read up on the various forms of doubling and good luck to you. There are many educational threads right here on the subject.
This coin exhibits machine doubling. It's important to mention though that there are several classes of doubled die. Some include those where a first impression of a hub is light while the next impression is normal. That results in the secondary devices NOT being raised to the same level as the primary devices. One of the 1909 V.D.B. DDO varieties comes to mind as an example of this. Thanks, Bill
This is true, though with the case of the 1909 VDB, there is still notching present on the coin that is indicative of hub doubling.
I was only referencing the depth of hubbings Yes, There is notching particularly on the RTY of LIBERTY.
Sorry it took so long to post the picture of the front of the coin. but here it finally is... Please let me know what you think.
Hi, The obverse was struck by a slightly misaligned die. Misaligned die strikes have to have detail missing to have any value. The reverse exhibits what is known as machine doubling. Machine doubling is not the valuable type of doubling. So, there is really nothing with extra value on your coin.
Ok, I am trying to understand this whole machine thing. I have read about it and I guess I still have't got it right. So here is another coin for everyone to look at. Is this MD or mint error?
Machine Doubling occurs when the ejection mechanism of the press begins the action of "pushing" the coin out of the coining chamber before the hammer die is completely clear of the coin. The end result is flat and shelf like. If you were to take a homemade "potato" die and press it into soft modeling clay but "move" the clay before the potato was clear of it, you would then be imitating Maching Doubling on a coining press. High speed coining presses have certain tolerance limits built in to both extend die life AND prevent the press from being damaged.
