If the pennies were pre-1982 then 9 US pennies are very close to 1 ounce (9.145 pennies = 1 ounce). If the pennies are after 1982 then 11 US pennies are very close to one ounce (11.34 pennies = 1 ounce).

For those who don't know, "dwt" is the standard abbrivation for pennyweight. The pennyweight was the weight of a silver penny in medieval England.
