Interesting...I'm a novice in this area so please take what I say with a grain of salt. My understanding is that Doubled Dies are created in the hubbing process. The die receives it's initial hubbing from the master die, but the working die is determined to be too brittle and needs to be "reannealled"...meaning, the die needs to be reheated and cooled to be less brittle. Once the working die is reannealled, it's carefully (and sometimes less carefully) realligned with the master die and the hubbing process continues. It's an error in this reallignment process that creates the doubled die effect. Doubled dies generally have some "focal point" where the dies are correctly aligned and there's a rotation around that focal point...devices further away from the focal point display the greatest amount of doubling. Your coin appears to have some sort of doubling of the profile, but I don't see any rotation on the rest of the coin. That would suggest something other than "die doubling". There's another effect known as "machine doubling" that can appear similar to "die doubling". Where the doubled devices on a "doubled die" appear complete and rounded...one device over another, the background device of a machine doubled coin appears flat...as if it were sheered off. From what I've read, machine doubling most often occurs due to too much pressure used during the minting process. The coin actual rotates slightly during the strike causing the "sheered" appearance. If I had to guess, I would say your coin is the result of machine doubling...but it's hard to say without actually seeing the coin "in hand". Hope this helps...or at least I hope someone with a better knowledge of the minting process can offer a better explaination.
Much of what you say is correct but remember the die Much of what you say is correct but remember the die in made from a hub, not another die. It goes liks this,,, Galvano produces master hubb, (positive image) master hubb prouduces master die (negative image), master die produces working hubb, (positive image), working hubb produces working die, (negative image), working die produces coins which of coarse are positive. It is generally during the second to last phase (working hubb to working die) that doubled dies are made, not always though as there is about 10 different types of doubled dies. Please remember that I left out 10,000,000 other words needed to fully understand this entire process.
