Sorry I don't see any doubling. And don't forget.. the correct term is Doubled Die not Double Quote - "Note that the proper terminology for this occurrence includes the letter 'd' at the end of the first word, hence "doubled die". The term "double die" without the first word ending in 'd' is not proper numismatic terminology." closed quote https://en.wikipedia.org/wiki/Doubled_die BIG difference
This is a real question. I don't do US coins, but I know about ancients. Why do people use the term "doubled die" when in ancients we see such a coin (like @paddyman98 showed us above) we call it a "double strike" and think the die bounced a bit when struck so it hit the flan twice, or it was struck twice with the die in slightly different positions. Do US collectors really think the doubling was in the die and not in the strike? Or does "doubled die" just mean the die was impressed into the coin twice?
A true doubled die is a result of the die, not the strike. There are plenty examples of a coin being struck multiple times, but this is not the same thing at all.
Interesting comment As Kirkuleez stated.. he is correct. And that's why I try to correct the person who uses the term Double instead of Doubled. I also mention "Big Difference" The Doubled Die is not a Double impression or else all the other images on the field would be doubled. So a Doubled Die and a Double Strike are 2 totally different occurrences
Many years ago, folks didn't give a darn if you called it a double die or a doubled die. Still today, most are good with either term.
Am I correct in believing Ancients used hand-carved dies? More recent dies employed a Master Die (a negative just like the production die), machine-copied from a much larger original, which were then used to create positive-relief hubs ("Working Hubs") from which the actual striking dies were created. These production dies ("Working Dies") were impressed (while annealed) by the hubs, and it generally used to take more than one impression operation to get the design fully imparted. It's imperfect alignment between successive hub impressions which result in doubled dies.
Andy, I think it's Coneca DDO-003 and here's the link to Coneca site . http://varietyvista.com/01a LC Doubled Dies Vol 1/1955PDDO003.htm There's also a die clash under lincoln throat .
Fun answer. It took a minute, but the answer is: 1960, with the 13th Edition. First listing of the 1955 doubled die, page #84. FYI: Ken Bressett was the individual who coined the term: "doubled die'.
