Is there a difference between Piefort & 2oz coin ? 2 2

[Ameeer]

 

hi 

I was wondering are they the same thing or is there a difference between them , any thoughts ? 

[Fenntucky Mike]

Yes,

A piedfort is a thicker than normal planchet. A modern bullion "coin" 2oz piedfort could be the same circumference as it's 1oz counterpart but thicker, a 2oz "coin" in comparison to a 1oz version would be the same thickness but have a larger circumference. Sizes will vary depending on the series, metal, denomination, etc. of the coin.

but how much is the thickness? is it exactly doubled ?

A 2 oz coin weighs 2 oz. 

a piedfort coin is thicker than the non-piedfort version of the same coin, usually twice as thick and twice the weight

Usually

I could be totally wrong on this but all the [phographs] I have ever seen suggest these piedforts are double the thickness of smaller coins, usually no larger than a U.S nickel.  I am not aware of larger piedforts the size of U.S. halves or dollars.

Engravers may work on larger pieces but these are not "coins" and to my knowledge are never referred to as such. Occasionally, you will see the term "essai" used with piedfort which suggests a proposed design for a new contemplated series.  

I do not believe a piedfort, which commonly precedes a series will be found in the middle of one.
