[QUOTE="Clawcoins, post: 3507473, member: 77814"]You should search out and learn about machine doubling aka mechanical doubling, etc. You'll learn a lot. By learning what Doubled Die isn't, you are going to learn what Doubled Die is. MD, etc is when the machine, through wear, or slippage, etc causes the illusion of "doubling". Remember "quantity" .. these machines are producing 250 to 800 per minute!! Proof coins are done 6+/- per minute by comparison. Real "doubling" is when in the process of making the "dies" themselves, somethings get stamped again slightly off and creates Doubling. there's tons of websites, etc dedicated to learning about it.
