Alright thanks one thread got it. I have a hard time telling the difference between the two. Sometimes I'll see something posted and think( wow that's nothing and it's a ddo?) My question is wouldn't a mechanical doubling occur throughout the entire coin? because it's it's machine striking twice not an error on the die right?
Doubled dies are not struck twice, and neither is MD. Doubled die coins are often confused with double-struck coins which look completely different. A ddo happens when the master hub (the die on which the coin is engraved) was being transferred, or 'hubbed' onto a stronger piece of metal. The master hub can slip or be rotated during this process which is what causes the doubled die. That is why it is also sometimes called 'hub doubling'. A double-struck coin would look like this: Hopefully, that clears it all up for you.
@dirdanic …study the minting process at John Wexler’s website (doubleddie.com). When the coin press is operating it is striking almost 12 coins per second. Someone please correct me if that is a tad too high, but it is close. There is no second intentional strike for any coin produced as a business strike. Proofs do get more than one, but the two production processes are vastly different. Also, the Mint uses one die pair for around 1 million coins or more, give or take a few thousand. This gives rise to hundreds of thousands of die deteriorated coins, in various stages of deterioration, depending on the aging of the die pair. Learning these processes will make you a better collector…good luck and happy hunting!…imo…Spark
Thanks all of you I definitely am interested to know the process and appreciate you taking to time to help and respond. Before I do look it up would this be a doubled die?
