Based on the provided source material, the 1961 Franklin half dollar was struck in 90% fine silver. This composition was standard for all United States dimes, quarters, and half dollars minted for circulation prior to 1965.
While the provided text confirms the percentage of silver, it does not state the coin's total weight. According to established numismatic specifications, a standard Franklin half dollar has a total weight of 12.50 grams. With a composition of 90% silver and 10% copper, the actual silver weight (ASW) in a 1961 Franklin half dollar can be calculated.
The total amount of pure silver in the coin is 11.25 grams, which is equivalent to approximately 0.36169 troy ounces. The copper was added to the alloy to provide hardness and durability for circulation, but the coin's intrinsic melt value is determined by its silver content.
