Same as a regular nickel, 5 cents. They're actually bison nickels, not buffalo nickels, and were issued as part of the Lewis and Clark Bicentennial. The last Indian head nickels were dated 1938; ALL nickels since then - including the bison ones - have a picture of President Thomas Jefferson.
All 2002 nickels have a picture of Monticello on the back. The only Jefferson nickels to carry an image of a buffalo (actually a bison) were dated 2005 and they're only worth face value if you find them in change.
Buffalo nickels were minted between 1913 and 1938. The coin you are asking about is a Jefferson nickel with a bison reverse, part of the Westward Journey commemoratives. They are not rare and are worth face value.
These are very common coins. They were made by the millions. You might get 3-4 dollars for your coins.
If you found it in change, it's only worth face value. Almost all of these coins were snapped up as soon as they entered circulation. FWIW the US has never minted a "buffalo head" nickel. The special Lewis and Clark commemorative nickels minted in 2005 are simply "buffalo" nickels because they show the entire animal.
No 2005 Bison Reverse nickels were struck in silver.
The 2005 nickel with a buffalo on the reverse is worth exactly 5 cents.
All Buffalo Nickels 1913-1938, Jefferson Nickels 2005, Kansas state quarter 2005, North Dakota state quarter 2006
This would be very rare coin because the Bison reverse was only used on the Jefferson nickels in 2005 not 2008. Look at the coin again.
Five cents, if you found it in change. ALL buffalo nickels, original (1913-1938) and modern (2005) are anatomically correct.
5 cents.
"Buffalo", but not "buffalo head". These nickels show the whole animal! These coins were minted for the Lewis and Clark Bicentennial. Hundreds of millions were minted and almost all were snapped up as keepsakes. Any that you find in change will be worth 5 cents only.
Please check again and post a new question. Classic buffalo nickels were minted from 1913 to 1938. A variation on the design was used on nickels minted during the first half of 2005.
