coop Bedrock of the Community United States 62064 Posts	Posted 05/19/2011 2:34 pm Die varieties are made on the dies during the hubbing process. Not when a die wears and shows it's age. Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 05/20/2011 12:07 am I would call it a normal coin. If its BU, then its a BU 2011-D Cent. Would I save it. I might, but mark it with a designation that you will remember what it was. Report this Post to the Staff
KenRingold Pillar of the Community United States 594 Posts	Posted 05/20/2011 09:55 am If a coin with these marks is normal, then a coin without them would be abnormal? Mark it with a designation as what, "normal"? Report this Post to the Staff
timsumrall Pillar of the Community United States 1256 Posts	Posted 05/20/2011 10:43 am I would use Die-deterioration doubling or simply DDD Report this Post to the Staff
KenRingold Pillar of the Community United States 594 Posts	Posted 05/20/2011 12:25 pm I don't know. To me it seems that if it was not done intentionally, and it is not a variety, then it was done in error. Thus, an error coin. Quote from the glossary "error - A numismatic item that unintentionally varies from the norm." Report this Post to the Staff

No, they would both be perfectly normal. If you grabbed a random pile of circulating coins, you could probably find some degree of Machine Doubling on half of them. You need to stop thinking of coins as if they are meant to be "perfect little objects" the moment they come off the press. In reality, all mass-produced items have certain tolerances that must be met during production- there is always some small level of inherent defects allowed in every product. Machine Doubling, small chips, cracks, and Die Deterioration all fall within normal mint tolerances. Report this Post to the Staff
westnlas Valued Member United States 85 Posts	Posted 06/24/2011 5:00 pm This is MD. The one way I tell is to simply look to see if there is a lot of doubling of different characters in the same position. That shows the die moved ever so slightly as it compressed the planchet. A true "double die" is an error in the engraving of the die itself. As the engraving shifted a bit when being carved into the die. This produces a different effect when the coins are stamped. The cent you show has obviously been doubled by the stamping process, not the engraving process. I would toss it aside for now and hang on to it for conversation value. I mean you only have 1c invested, and it's a cool coin to show friends and talk about. Report this Post to the Staff
