Just out of curiousity, what is the other .1% ?

I suspect that it is probably mainly zinc, copper or lead, as
these metals are used in the refining of silver.

So a "one ounce" gold or silver coin such as an American Eagle
is a Troy ounce?

Yes.

"Coin silver" is 90% silver, 10% copper. Does a one-ounce silver
coin contain one ounce of silver, or a total weight of one ounce with
90% of that being silver?

The US Silver Eagle is not coin silver, it is 99.9% Fine, and contains
one Troy Ounce of Silver.
