Some one who knows how a cent with double year, double mint mark, double nose, double upper lip, can be classified as hubing please enlighten me as to how this can happen..I send to grading service and got this answer..So I called and ask for them to explain..Explaination was if I take baseball bat go out front and strike the flag pole it is going to vibrate..And he is correct..But does just the side that is struck vibrate or the whold pole..Half ot a penny can not move without the other half moving so I really don't know how this error can happen..It is just not possible for half a die or half a planchet to vibrate or move upon being struck..Of course now you just have to take into consideration that I 'am not a math. geniur..Just a little common sense approch..Any other suggestions would help..Thanks....
If you coin looked like this, then it was doubling. I got this valuable lesson from MR. Wexler, his site will show you all kinds of examples of this..Hope it helps and keep searching!!
Definitely not hub doubling. If the face/portrait of Lincoln is doubled as well, it is most likely machine doubling. Machine doubling occurs when loose dies shift slightly as they strike a coin, leaving a doubled appearance. Keep up the hunt!
Most likely they meant master hub die doubling. If the master hub/master die operation involved a movement, then the master die could be doubled and all working dies made from that master die would be doubled, and the doubling would be so common, that they would have no additional value. Usually minor and often not noticed until after production. A flat shelf like doubling ( MD) is common on the 69-S, but I do not recall master hub doubling. I would look carefully to be sure it is master hub doubling or MD.
Using the flag pole how does it shift only on half the collar on blank is pretty tight..it has to strike twice for you too see two images..Sorry but just don't buy the reasons given..I know it is all just Opinion and thanks for the input...Just can't wrap my common sense around the theroy...
Sometimes a coin is struck twice, but that is not the "doubling" that is discussed above. The die that is used for the striking of the coin directly is called the working die. It is made by pressing a die blank against a working hub with a positive design, which is turn was made from a master die ( negative design) which in turn was made from a master hub ( positive design). The only process where striking occurs in the last stage on the planchets. The transfers from hubs to dies occurs by a process of pressing the two ( hub-die) together with great pressure. This process hardens the metal, so they are separated and heated to soften the die which is then taken to the press and squeezed again with a hub ( IF they are aligned, all is well~ if one is slightly rotated or tilted in the process of squeezing , then a doubled die will be produced. It is a cascade process, so if the doubling occurs in the earliest stages, all of the succeeding dies will show it and it will be of little significance as it is extremely common ( master hub doubling). If it occurs in the last stage, it is only on the coins struck by that single die out of thousands of dies. When "Single Squeeze Hubbing" came into being, the removal/heating/reinserting stopped and only a single squeeze under very high pressure was thought to eliminate doubled dies, but it just produced them a different way. Think of the flagpole, with a 8 ft circular base being removed from the ground and then reinserted anew, the chances it would be a little off or slightly tilted may seem easier to understand. Jim
Well if the pole is pulled out of the ground and reinserted is the whole pole a little off and slightly tilted or just half of the pole again the reason doesn't get me away from the fact that it is half stamped and not completely stamped when dies are solid objects and planchets are solid pieces..You got too have a complete doubling on a rotation, There is just no in between half way...Don't believe it is math possible to happen..Sorry guy gave the High school pro and con debate team hours of though process..My Teacher under my picture put these words "speaks softly carries a big stick" Still not real sure the complete meaning....
No I don't have a camera or know how to use this computer..It is in a graded holder at this time..Anacs does not photo their grading...
I use this machine to read and get a better understanding of coin hobby..when I started this venture..we did not have all the variety that is out here today seems something get declared a new variety every day..
There are several different types of hub doubling. Rotational hub doubling as is seen on the 1955 and 1972 DDO cents is the type that most people think of and it does create a doubled image all over. But the other types can create doubling that is only present in some areas and not others. One case could be distorted hub doubling where the die when annealed between hubbings does not expand and shrink evenly so part of the image is not in the same place as it was in the previous hubbing. That can create doubling in just one part of the design and not others. If your coin is showing the same doubling on the mintmark as on other features then it is most likely NOT hub doubling. In 1969 the mintmark was not part of the hub and so something that doubled the image in the die would NOT be able to double the mint mark as well.
Now the mintmark sheds light on subject that I have never heard expressed or discussed year and mintmark are doubled, His nose is and upper lip..The year and mintmark is a shift to the west or left and slightly south. Nose and lip is shifted to the west ..Now down the front of clothing there is no shift around the bow tie..Thanks...LJ
