wrongalot Pillar of the Community United States 608 Posts	Posted 10/18/2007 05:22 am Here is another example of mech. doubling. Sorry about the pics using a different camera, some came out ok some didn't. At a glance you can see that some of it looks mechanical, some are double strikes, but some actually look doubled, weird nickel. Lets hear some opinions......

wrongalot Pillar of the Community United States 608 Posts	Posted 10/19/2007 4:16 pm yes, they are all mechanical, I meant to say that they are raised, like doubling, but no seperation, and coppercoins can correct me if I am wrong, but I believe there has to be some seperation in order for them to be considered doubling.

coop Bedrock of the Community United States 62064 Posts	Posted 10/19/2007 5:00 pm If they are Mechanical Doubling, they can't be called die doubling. A doubled die is that: A die that has been hubbed with a separation between hubbing. Mechanical Doubling regardless of how much is doubled, is never a doubled die, but a machine that has some looseness of the mechanical parts. It turns the strike in an error. Some example of the same die pair can mechanically be different or normal. Its just an error of the machine. A variety is made on every coin that has a hub doubled die/repunched date/RPM/over mintmark. This is evident on every coin made from that die. Hope this helps. Report this Post to the Staff
foundinrolls Pillar of the Community United States 3507 Posts	Posted 10/20/2007 11:58 pm Too many concepts in this thread that need repair:-) Separation is not always present on coins struck by doubled dies. Some doubled dies have very close spreads, as we describe them so that there is no actual separation visible. We see notches and splits on the serifs and we can see grooves in the lettering but not always separation. Mechanical Doubling is not always a result of loose mechanical parts. We consider die fatigue doubling a form of Mechanical Doubling and that has nothing to do with parts being loose. Report this Post to the Staff
