A US 5¢ coin weighs 5g. One ounce is 28.35 grams, so you can get 5 nickels in an ounce, with 3.35g to spare.
You could have: 8 nickels and 1 penny or 6 nickels and 11 pennies or 4 nickels and 21 pennies or 2 nickels and 31 pennies. The option of 0 nickels and 41 pennies is excluded by the necessity that the amount is made up of dimes, nickels and pennies; 0 nickels would mean the $1.21 was made up of dimes and pennies only.

US nickels made from 1866 to mid-1942 and from 1946 to the present are made of a copper-nickel alloy, not silver. From mid-1942 to 1945 nickels did contain a small amount of silver because nickel metal was needed for the war effort. Those "war nickels" are the ONLY ones that have any silver in them. Because dimes, quarters, and halves contained silver up till 1964 many people erroneously believe that nickels did, too. But after all, the coin is called a nickel because it's partly made of nickel!
