Probably a couple of dollars in a gift or novelty shop, unless it's made of some kind of precious metal which should be indicated somewhere on the coin.
All genuine buffalo nickels are the same size as modern US nickels, but many companies make replicas that are much larger or smaller than the real thing.
Like all US nickels except the famous "war nickels" of 1942-45, buffalo nickels are made of an alloy of 75% copper and 25% nickel. Regardless of urban legends and internet rumors, the US never made any other silver nickels except those struck during WWII. There were in fact tiny silver 5-cent coins called half-dimes but they were discontinued in 1873 and were never called "nickels".
The Federated Metals Corp bar Marked XXXX Nickel is babbit. It is approximately 85% tin with the balance being Antimony, Copper, and a tiny bit of Nickel. Nickel will stick to a magnet in the same way Iron will. These bars will have no pull to a magnet at all. As far as metal they have very little value. They may have more value as a curiosity or to a collector.
Half-dimes were tiny (14 mm) coins issued up till 1873. The reason your coin is the size of a nickel (21 mm) is that it IS a nickel. However, without a date it's not possible to give a specific value. Please enter a new question in the form What is the value of a [date] US nickel? for a specific answer. (date = your coin's date)
You need to know the coin's condition, date, and mint mark. A buffalo nickel without a date (a common problem until the design was modified in the mid-1920s) is called a cull and is only worth 10 or 15 cents. If you can see the date, look on the back under the words FIVE CENTS to see if there's a tiny letter. It may not have one, or it may have a D or an S. You can then look at this site for questions in the form "What is the value of a (date) US nickel?" for more information.
From any coin dealer. If you know the date, mintmark, and condition, you can look it up at several places online or in price guides that are sold in most bookstores. For an online retail price guide, see the related links or go here : http://www.numismedia.com/fmv/prices/bufnkl/pricesgd.shtml
The Terror of Tiny Town was created on 1938-12-01.
There's no such coin. If you have a large (38 mm) coin with a picture of President Eisenhower on the front, it's an ordinary copper-nickel dollar that was plated with a tiny amount of gold, and has no extra value except as a curiosity.
The cast were all little people
Microorganisms inside its digestive system help the buffalo digest the food it eats. In this kind of symbiosis, both species are helped. The tiny creatures have a meal brought to them, and the buffalo can digest grass and leaves.
This famous design is called either a buffalo nickel or an Indian head nickel; both names are about equally common. Look on the back under the words FIVE CENTS for a tiny letter. That's the mint mark that tells where the coin was made. Retail values as of 09/2008 are roughly: No mint mark (Phila.) : $1 if very worn, $6 if moderately worn, $10 with almost no wear. D (Denver) : $8 / $25 / $130 S (San Francisco) : $17 / $90 / $600, plus or minus.
Assuming you have a buffalo nickel (i.e. FIVE CENTS on the back, correct?) it's an ordinary nickel that's been plated. Unfortunately the plating destroyed its numismatic value. It could have been worth about $3 in average condition but with plating it's only a curiosity piece.
$1. There were no gold dollars struck that year, only copper-nickel. Your coin has been plated with a tiny amount of gold that would cost a lot more than a dollar to remove.
