You could try a dealer or an auction site, but it may not be worth it unless you have a large number of coins. As of 10/2015 uncirculated US nickels retail for about a quarter so you might get all of 10 or 15 cents for each one.
You might try a coin dealer or an online auction site like eBay, but it may not be worth the trouble unless you have a large number of coins. As of 10/2015 uncirculated 2006 nickels retail for about a quarter, meaning you'd be unlikely to get more than 10-15 cents each selling them.
So many were made that most uncirculated 2006 US nickels retail for less than 50 cents. Very high quality strikes (MS64 and above) can retail for $2 to $15, though.
So many were made and saved you are better off spending them, they are still in circulation.
Liberty nickels were minted from 1883 to 1912. All nickels minted since 1938 have been Jefferson nickels, and ALL US coins carry the word Liberty. In any case your coin is common; any that you find in change are only worth face value. A nice uncirculated one might sell for 25 to 50 cents.
It depends greatly on the year and mintmark. For example, if you go to enough banks, you will most likely find an uncirculated roll of 2013 nickels sold to you at face. On the other hand, for uncirculated war nickels (1942-1945) or other early date Jefferson nickels, they'd be worth much more.
Face value.

Please check your coin again. All 2006 nickels show a picture of Monticello on the back."Bison" nickels were minted in 2005. If that's what you have, it's only worth face value if you got it in change. A nice uncirculated one might bring 50¢ to $10 depending on its quality.
These are all considered to be common dates if in circulated condition. Worn, they sell for about a dime. Even in uncirculated condition, most retail for a couple of bucks at most.
IF you can find a buyer, the coins might sell for 10 to 20 cents each. However most dealers probably have all they want or need. You may have more luck posting on an auction site, but shipping and insurance will probably eat up any profit you might make.
Only face value unless you find someone that wants them.
