Collectible coins have a value based on individual condition, and the market for buyers. This is especially true for the Ben Franklin coins 1948-1963 and the earlier Liberty Walking halves. But even average circulated coins have silver content thru 1969. Half-dollar coin values based on the silver content (90% through 1964, 40% to 1969) : 1971 or later - 50 cents
1965-1969 - about $2.50, varies with the price of silver
1948-1964 - about $6.00, varies
Before 1948 - please post a more specific question with the coin's date and mint mark.
