What is the value of a 1957 US half dollar?

All Franklin half dollars were made of 90% silver, but 1957 is not a rare year. In lower grades the coin's value is mostly determined by the value of the silver it contains.

Look on the back of the coin to see if there's a small mint mark letter just above the Liberty Bell. It may be blank or there may be a D.
