how much silver in a roll of 1964 half dollars

[OEli]

A standard roll of 1964 Kennedy half dollars, which has a face value of $10.00, is comprised of 20 individual coins. The metallurgical composition of these specific coins is the determining factor for their total silver content. According to the provided information, each 1964 Kennedy half dollar was minted with a composition of 90% silver and 10% copper.

Based on this 90% silver composition, a single 1964 half dollar contains 0.36169 troy ounces of pure silver. To ascertain the total silver content for a full roll, this per-coin amount is multiplied by the number of coins in the roll.

Therefore, a complete 20-coin roll of 1964 Kennedy half dollars contains approximately 7.23 troy ounces of pure silver. This is calculated by multiplying the 0.36169 troy ounces of silver per coin by 20 coins. It is worth noting that some sources may cite a slightly lower figure, such as 7.15 troy ounces, which is a common industry approximation that can account for potential weight loss from the circulation of coins. However, the figure of 7.23 troy ounces more accurately reflects the total silver weight based on the original mint specifications for uncirculated coins.
