I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the blanket of the very freedom I provide, then question the manner in which I provide it. I prefer you said thank you, and went on your way, Otherwise, I suggest you pick up a weapon, and stand to post. Either way, I don't give a damn what you think you are entitled to!

machine/shelf doubling
neat though.
Too many positive BST transactions with too many members to list.

If the coin shifts, wouldn't everything be doubled ?

You're right, machine doubled coins got a second kiss from a normal die.

Machine doubling damage (MDD) has been a topic that I have researched and written about for close to 30 years. Curiously it is a topic that has been virtually impossible to "sell" to the collectors and dealers. Since it affects world coins, it will be this week's topic.
Anyone who has looked closely at a quantity of coins has seen it. It's the most common form of doubling found on coins. It has appeared under a laundry list of names, such as "shift," "micro-doubling," "double die," (Not doubled die), "strike doubling" and most recently as MDD.
