When Congress authorized the Franklin silver half dollar in 1948, it was expected to be issued for at least 25 consecutive years. But following the tragic loss of President Kennedy, Congress quickly approved a new half dollar in his honor, abruptly supplanting the Franklin series. This proved to be the last American coin series completely struck in traditional 90% silver.
This 1953 issue was produced at the San Francisco Mint and had a low mintage of just over four million. In comparison, Denver output nearly 21 million Franklin halves that same year.
