2009 proof dime, get your glasses

Well, I suppose that's OK if you just need a quick back-of-the-envelope estimate...

Dang...wish I had said that...

 

Ha, hope you aren't setting me up I have looked at it several times and passed over answering. But asked directly, I would consider it if mine for the price of a non-DD, no more. Nice coin, but I really do not see any feature to say DD

I believe there is an error in line 6, don't you ??

 

Not at all.

You're one of the few who has taken the time to repeatedly address the difference between single squeeze "doubled dies" and those produced by the classic hubbing process, so I was simply curious as to if you had any thoughts on the matter.

As always, I much appreciate you taking the time to answer the tag.

 

I was just kidding. I do think that the Single squeeze DD or DR is mechanical, obviously when one examines the production of modern SS dies.

One should pay attention to the type of production and inspection ( near the bottom of that url) that would seem to eliminate any type of 'doubled' die from getting into production. To say that the master die ( created by Phila. mint CNC machine) is a one cut process and the master is not doubled at that point should be a given). This master die is hubbed once rather than multiple, and any single squeeze doubling on the hub die does not reflect that master die, but mechanical vibration of the master die against the hub die. This mechanical doubling is transferred to a coin when produced, but that does not make the hub die, which will produce the coins, a doubled hub, just a mechanically damaged one. Since all coins of a certain SS type (such as a California state quarter) are not 'doubled", just from certain hubs, should indicate it is a mechanical problem and thus not of numismatic significance.
I believe that people who make money off of the plethora of SSDD euphoria, from companies to individuals are responsible for the misinformation. I do admit that it can lead new people into the hobby, but it also gives false expectations and leads to many misunderstandings. IMO Jim
