Double Die single squeeze hub??

[willbrooks]

Jim made mention of a very important part of single squeeze doubled dies. Many times, the technician started the hubbing process and for some reason or another stopped and then restarted the procedure. Upon activation of the machinery the second time, the already hubbed portion of the die is then rehubbed a second time (a doubled die) if all of the settings and positioning were not perfect. This seems to be how the majority of the more major single squeeze doubled dies are made. The Mint has admitted on occasion that this was an issue they had hoped to curtail, so it is not a theory. Obviously, it still happens. Some years have hundreds of minor doubled dies, especially statehood (Minnesota) and America the Beautiful (Homestead) quarters.

Yes. I find that there are at least 2 different classes of "single squeeze" doubled dies. The "start, stop, and restart" accounts for the myriad of centrally isolated doubled dies like the extra fingers and such. However, it does not explain the other doubled dies we also see in recent years. I have a new thought on it and am studying now. Not at all certain of anything though at this point.

Thank you Will for the update on your study! I've been wondering how it was going and what your findings are!

Yes it helps a lot I thank you for the help. I can see how both theories are correct. Steve

Interesting I can’t thank all of the input. It really helps understand the single squeeze and makes studying and collecting a lot more interesting. THANKS. Steve
