There were 39,559,372 minted, while that doesn't say how many survived the 99 years since 1911, it is the most common year out of all the other years in the "V" nickel series.
38,612,000 Liberty Head nickels were made in 1906. All were struck at the Philadelphia Mint.
Liberty head nickels are made of the same metal as nearly all US nickels, an alloy of 25% nickel and 75% copper. The only time nickels had a different composition was during World War II. Special "war nickels" minted from late 1942 to 1945 due to metal shortages. War nickels were made of an alloy of 56% copper, 35% silver, and 9% manganese and can be identified by a large mint mark letter over the dome of Monticello on the back. Regardless of many popular misunderstandings these are the ONLY nickels that ever contained silver.
Buffalo nickels were not struck until 1913 so your nickels (which do not have buffaloes on them, correct?) must be from the prior series called Liberty nickels. You can find a price guide at http://www.numismedia.com/fmv/prices/libnkl/pricesgd.shtml , among many such sites.
