None.
Except for "war nickels" minted from mid-1942 to 1945, nickels have always been made of 75% copper and 25% nickel. War nickels had a small amount of silver in them because nickel was needed for the war effort.
The amount of pure silver in the 1922 Peace dollar is .77344oz, all US silver one dollar coins from 1840 to 1935 have this much silver in them.

1 Dollar "Peace Dollar" 1921-1935 Commemorative: End of World War I Silver (.900) - 26.73 g - ø 38.1 mm so 90% is silver of the 26.73gm total weight
As of 8/23/2012 300 grams of silver @ $30.5 oz troy = $272.15
a 1920 buffalo nickel is worth about 2.50 because it's not that rare
The Buffalo/Indian Head Nickel's composition was 75% copper and 25% nickel. The only war-time silver nickels were from 1942 to 1945. A well-circulated 1920 nickel values from 5 cents to 2 dollars. If never circulated with original luster and full horn in reverse could be over $100 for a 1920-D. If the color is silver toned or shiny then it could be the original strike or has been cleaned or dipped in a cleaner.
Buffalo nickels stopped being minted in 1938. If you're referring to a '44 Jefferson war nickel, then it contains 35% silver.
Sorry, no Buffalo nickels were ever struck in silver.
How much is a 1820 buffalo nickel
....none. All nickels with the exception of the ones minted during WWII (the ones dated 1942-1945 with the large mintmark over the Monticello contain 35% silver) are 75% copper, 25% nickel. There are no silver buffalo nickels.
The last Buffalo nickel was made in 1938. A 1942 dated Jefferson that has a large mintmark on the reverse is 35% silver and worth about $1.00. If it does not have the large mintmark just spend it.
The only years US nickels were struck in silver was 1942-1945. 1914 is a Buffalo nickel. Coins in average circulated condition are valued at $15.00-$30.00 depending on grade.
The 2005 nickel with a buffalo on the reverse is worth exactly 5 cents.
Please don't assume that because a coin is old it has to be made of silver. All buffalo nickels are made of the same 25% nickel / 75% copper alloy used in modern nickels. Internet rumors notwithstanding, NO buffalo nickels ever contained any silver.
There is no silver in a 1964 nickel.
Buffalo Nickels weigh 5 grams and are made of an alloy that is 75% copper and 25% nickel.
