Thank you silver stacker for taking the time to do this for everyone here on CCF.. I always have a problem when it comes to certain coins and trying to distinguish if I am looking at md or dd on certain examples but your simple breakdown makes it definetly easier for the new collectors to understand without having to read a book about it to understand the differences. I thank you for your time doing this.. I usually don't have issues but there are those coins that show both md and dd that really get me  . Props to coop as well for his efforts and all he does along with all the other pro's..We all appreciate your hard work here on the forum.  |

Yes we do appreciate it! Priceless help...I any have given up long ago on finding a doubled die if not for this forum-it look me almost a year and a half of hard searching before I found my first true doubled die and 5 more quickly followed and totally renewed my passion! I was told to keep looking I will find and at times had trouble believing I would lol but along the way I also started finding some other awesome errors but it does take time and commitment but I love it,every roll is like a new treasure hunt-I'm in another dry spell lol but that's just fine-good luck and keep searching...

Are you sure? Because people always say it differently. I will change it. :/

It is called a doubled die for a reason. When the hub creates a doubled image on the die, we call it a doubled die because the doubling is on the die. Machine Doubling (actually damage to the devices on a coin) is created from a normal die and the machine causes it to damage the coin. Die movement, ejection and probably other events make a coin from a normal die look doubled (damaged) I refer to this often as machine damage on a coin. some call it machine doubling/mechanical doubling/strike doubling/studder strike/and other terms. I call it machine damage/doubling because it came from a machine, not a mechanical. But that is just me. Edited by coop

Machine Doubling is an event that happens during the strike. Some will call it an error, but it is so common I feel it is not something I would call an error. Hub doubling is caused by a misalignment of the dies/warped hubs/altered hubs that make a doubled set of devices on the die. This is not an error, but a die variety. They will create coins that look like the first one until it is retired. (some allowance for die wear) The people who collect these are called variety collectors. I view as an error as a one of a kind of error. Wrong planchets, misalignment errors, incorrect strikes and events that create one of a kind coin. (coin struck through a spring/wire/cloth/staples/thread) The bigger the error, the more collectable it is. Then there are the ones called errors, that are just die wear/die cracks/chips/clashes/struck through grease/die breaks and other events that happen over and over. These I don't give much of a premium for them. Only when they become extreme. (die cracks across the whole die/cuds/extreme clashes and other events that usually create more than one) That is how I view collectables.

100% in agreement with your last post coop...i was putting all the somewhat decent die crack and die chips aside in seperate tubes but I started to hoard so many of them I'm only keeping extreme ones now-still looking for a full die crack tho across the entire coin
