Thank you so much!!!!!!! I should go back to middle school!!!! So it comes out 39 grams...much closer to the the 31 grams! Does someone own the platinum maple leaf? why the american platinum eagle is more expensive?
Don't forget that a coin is not a flat slug. It has depressions that are lower than the rim so the volume of a coin will naturally be less than the volume of a slug of the same dimensions.
