How many Silver Coins (weighing 26g each) would it take to provide 5 moles of Silver (Ag)?

5 moles Ag = 5*atomic mass Ag = ?? grams. But Ag coins are not pure Ag; in fact the percentage varies and some contain no Ag at all.
??grams Ag/percent(as a fraction) = ??grams coins.
Then ??g coins/26 = # coins
