How much is a 1964 Kennedy half dollar worth?

Answer 1

As of Feb 2012 it is worth $32-35!! 2> Answer

1964 is the most common year for silver half dollars. Even in uncirculated condition (unless it is an absolutely flawless gem), its value is based only on the silver it contains -- about $5 to $6 as of 06/2009

Uncirculated and proof coins are worth about $7-8

Metal composition1964 was the only year that JFK halves were made from 90% silver / 10% copper alloy. From 1965 to 1969 they were made of a "debased" silver clad 3-layer composition that worked out to 40% silver, 60% copper. By 1971 the price of silver had gone up so much that the composition was again changed to the same copper-nickel clad metal used for dimes and quarters.
