Hello! That's a great question about a classic American coin.
According to the provided information, the 1954 Franklin half dollar was struck in 90% fine silver. This was the standard composition for these coins during their entire production run.
To be a bit more specific about the exact amount, this 90% silver content means that each coin contains approximately 0.36169 troy ounces of pure silver. The other 10% of the coin's alloy is copper, which was added to increase the coin's durability for circulation. So, no matter which mint it came from (Philadelphia, Denver, or San Francisco), your 1954 half dollar will have that same silver content.
