I'm sure it's another Mechanical Doubling, but it never hurts to ask!

brefos77 Pillar of the Community United States 792 Posts	Posted 12/27/2007 8:25 pm Thanks. I gotta get "mechanical" out of my head. Stupid Machine Doubling, that'a all I ever find. Grrrr! Report this Post to the Staff
coppercoins Pillar of the Community United States 7629 Posts	Posted 12/28/2007 09:56 am Then you should keep a few examples marked as such and use them to compare new finds against. Then buy a couple of real doubled dies and compare them against the Machine Doubling. The difference between them is really very obvious. My 11 year old son can easily pick the difference. If you continually look through change for anything doubled without furthering your education in what to look for, you'll never break through the barrier and will always find worthless Machine Doubling.

brefos77 Pillar of the Community United States 792 Posts	Posted 12/28/2007 4:36 pm Thanks again, Chuck. I've been looking around and trying to compare the two in differences. On a true double. the "twin" is level with the original letter, number, or whatever is doubled. On a Machine Doubling, the twin is lower, like you would be stepping down from the original to the twin. Right? Oh yeah, about the mechanical/machine issue, I think this is where a lot of us rookies got that term from: http://coins.about.com/od/coinsglos...cal_doub.htm Thanks again!

coppercoins Pillar of the Community United States 7629 Posts	Posted 12/29/2007 6:59 pm Nobody in the business calls it " Mechanical Doubling" - basically Susan got her information from an unreliable source. As to your explanation of the difference between Machine Doubling and a doubled die - in essence you are correct, although there are exceptions to this basic description. If you use this as a rule, you will always safely rule out Machine Doubling, however there are some forms of hub doubling (doubled dies) that aren't always as high as the primary devices. Basic difference that will ALWAYS be safe is that Machine Doubling is a part of the device flattened down...hub doubling is actually two different hubbings of the device into the die.
