None. The Mint changed the composition to copper-nickel that year. 1964 was the last year that the US Mint produced 90% silver coins, but subsequent coins do contain some silver. Since then, dimes, quarters, and halves are basically a big penny with a silver wash, although they retain the ridges around the rim of the coin. This was originally done to prevent counterfeiters from scraping silver (and gold) from the edges of US coinage. There will be no percentage in that enterprise again unless the price of copper rises high enough to make it worthwhile.

And from 1965-1970 the half dollar was 40% silver and is worth about $4.50 in silver content. Half dollars dated 1971 and later are not silver unless found in a US mint silver proof set. Note that any half dollar made during 1965-69 is only partially silver and is worth about $3. Halves dated 1971 and later contain NO silver and are only worth 50 cents.
