A dateless Buffalo nickel is still worth 5 cents. Some people use them to make jewlery out of and will pay a little more.
By "type" I assume you mean "mint mark" because there are no known design varieties for 1926 nickels. The mint mark position on all buffalo nickels is on the back under the words FIVE CENTS. No mint mark = Philadelphia, S = San Francisco, D = Denver. Philadelphia issues are common; as of 01/2009 retail values range from $1 if worn to about $10 if almost like new. 1926 Denver nickels are harder to find - their range is $8 to $150; San Francisco nickels are the scarcest for that year with a range of $17 to almost $1000.
The value of a 1926 buffalo nickel can vary based on its condition and mint mark. Generally, it ranges from a few dollars for lower grades to around $20 or more for uncirculated examples. A 1926-S, minted in San Francisco, is particularly rare and can be worth significantly more, often exceeding $1,000 in high grades. Always consult a coin dealer or price guide for the most accurate valuation.
Value is determined by the coin's date, mint mark, and condition.
There's no coin called a "buffalo head" nickel - it shows the entire animal! Assuming the coins are circulated and have no mint marks, the 1936 Indian Head nickel (note spelling) is the highest mintage of the series, most only have values of $1.00-$3.00. The 1926 is a little better at $1.00-$5.00. There's more-detailed information at the questions "What is the value of a 1926 US nickel?" and "... 1936 US nickel".
The U.S. mint did not issue a nickel with a buffalo on it in 1867.

The value depends on the date, mint mark, and condition. Without knowing those details, your question is impossible to answer.
