When Does Machine Doubling become a Double die?

[Bruceswar]

What is the differnce? I mean I know what the difference is but... where do you draw the line on it?

[solid]

There really is no line to be drawn.

 

Doubled dies are just that; doubling that is a part of the die itself and will impart the identical doubling to every coin struck from said die.

 

Machine doubling happens as a result of loose dies that may "twist" as the coin is struck, creating the flat shelflike doubling. You tighten the die down and this doubling goes away.

I know that the 2 are different... but if the machine doubling is rather large then?

[solid]

It will still be machine doubling, and while perhaps interesting, will never be as rare, desirable or valuable as doubled-die examples.

 

Just my opinion!

There is no line to draw between the two as they are separate entities. Even very broad machine doubling will not have split serifs whereas a doubled die will. If you pick up a copy of The Cherrypicker's Guide you can read a nicely written description of each.
