The 1964 Kennedy half dollar is a 90% silver coin but so many were made only a very high grade uncirculated example is worth more than the silver in the coin. The silver value today (3-16-11) is about $12.00.
The US didn't release any one dollar coins that year. It might be a 1964 Peace dollar, in which case it's actually from the 1920s and the date was restamped later. One of those is currently worth about $13 for the silver.
