A standard roll of Franklin half dollars contains approximately 7.15 troy ounces of pure silver. This total is based on the specifications of the coins and the standard quantity in a roll.
A complete roll of Franklin half dollars consists of 20 individual coins, resulting in a total face value of $10.00. Each of these coins, which were minted from 1948 to 1963, is composed of an alloy of 90% silver and 10% copper. This composition was the standard for United States silver coinage prior to 1965.
Consequently, while the gross weight of the 20 coins is higher due to the copper content, the aggregate amount of pure silver across the entire roll is calculated to be approximately 7.15 troy ounces. This figure is the standard measure used by numismatists and precious metals dealers when assessing the bullion value of a full roll of 90% silver Franklin half dollars.
