God willing we get some news soon before we wind up "Board Of The Flies"

maybe some of you savey folks can help me with a question -

I am looking at silver coins and I see that the American Eagle is .9993 pure and the Maple Leaf is .9999 pure - apparently the American Eagle has a hardening alloy.

Also the American Eagle trades at a premium above the Maple Leaf - Is there some reason to buy the more expensive less pure American Eagle over the less expensive more pure Maple Leaf?
