DDO Or Machine

MD Perrty sure it looks flat.

phazon what do you mean by flat?

Machine Doubling Machine Doubling (also called Mechanical Doubling, shift doubling, or Strike Doubling) is very different from Die  Doubling.  Machine doubling is created when the die shifts slightly as a coin is being struck.  Machine doublingis  the result of loose mechanical parts that cause a poor strike.  In machine doubling there is no doubling in the  die, just in the strike.  In a Doubled Die, the die itself contains the abnormal doubling.   Die doubled coins are  considered varieties, and are often valuable.  Machine doubled coins are considered errors, and are not of any  significant value to collectors. In machine doubling, the secondary image is often a flat shelf-like surface.  In Die Doubling, the  secondary image is rounded and looks similar to the primary image.  A tell tale sign of machine doubling is when  the mintmark and date showthe same doubling.   I see machine doubled coins sold on ebay almost every day.  Below are some pictures.  My advice is to not  purchase any doubled die coins that you have not seen pictures of in a book or website.  The Cherrypicker's  Guide to Die Varieties gives detailed descriptions of how different types of doubling are created.  This article is from Lincolncent Resource

So then most if not all Doubled Die errors would be listed. would it not be rare to find one that is not. Maybe the internet(google images) is whats throwing me off. I see pictures there claiming doubled die that are actually MD. So now I know. there are a lot of people that are being suckered by this. I myself have never bought a coin claiming an error I just look at every coin that comes my way.
