Question
troy,
I am in argentina so by email is it
the eagle weight is 1.10 oz to allow for the copper added and still have oz gold. again, yet here is a .999 coin buffalo   weight one oz so it should be easily smaller than eagle yet is is larger!!!!!
Panda and buffalo same weight but panda much smaller...i doubt the panda imagine makes up for size...

Answer
Hi Jared,  If you weigh and assay each of the coins you will find they are all within the gold content specs specified.  Again, you are not taking into account the relief of design and the exact dimension throughout the coin (ie You are missing data on each coordinate throughout the design because you only have diameter and thickness of the rim).  On the American Eagle you would also need data on metal densities.  Thanks!! Troy
