This is a American Silver Eagle 1 ounce bullion coin. The value is tied to the spot price of silver at the time of sale. As of 3-13-12 it's $33.64 per ounce. This price is a little less than you could buy it for and a little more than you could sell it for. But it gives you an idea of value. Collectors versions of this coin do have higher values.
NOTE: The spot price of silver and other precious metals changes by the minute when the market is open. So the value of this coin will go up and down.
Liberty head quarters, more frequently called Barber quarters after their designer, were minted from 1892 to 1916. If your coin is dated 1925 it's called a Standing Liberty quarter because as you can tell from the image, it shows all of Miss Liberty, not just her head. Please see the Related Question for more.
Only Liberty Head half eagles were made in 1904. The first Indian Head was made in 1908.
Please check your coin again and post a new, separate question. A 1936 dime would have a picture of Miss Liberty on it. The only 1936 coin with an Indian head design is the nickel.
The date on a half-eagle gold coin should be on the front of the coin underneath the head (Liberty or the Indian). And on the 1/10 ounce American Gold Eagle, the date is to the right of the personification of Liberty.
Your 1925 Liberty coin is actually a 1925 PEACE dollar, this series of "silver dollars" were made from 1921 to 1928 & 1934 to 1935. The 1925 date is very common and assuming the coin is circulated and has no "S" mintmark retail values are $16.00-$20.00
The first Indian Head Half Eagle ($5) gold piece was struck in 1908. A coin of this kind dated 1880 would be a Liberty Head gold coin. Please check the coin again and post new question. Also look on the back of the coin for any mintmarks.
That description applies to any of a number of coins. Please post a new question with the coin's date and denomination.
The 1925-D Indian Head Quarter Eagle is a common date coin of the series. For an accurate assessment of value the coin needs to be seen and graded. Assuming the coin is circulated, retail values are $250.00-$350.00 depending on the actual grade. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched, used as jewelery or have been cleaned have far less value if any to a collector or dealer. NOTE: All 1925 quarter eagle coins were struck at the Denver Mint. The "D" mintmark is on the reverse, to the left of the arrows.
There were no Indian head dollar coins. If your coin is large (about 38 mm) and has the word PEACE on the back, the image on the front is Miss Liberty from the Statue of Liberty. In that case, look for a small S on the back near the word ONE. If there is no letter, the coin is worth about $15. If the S is present, it's worth $15-22 depending on how worn it is.
The coin is NOT a Liberty silver dollar, it's a PEACE dollar (1921-1935) and assuming the coin is circulated and has no mintmark, retail values are $32.00-$37.00 depending on the actual grade of the coin. 1925 is a common date.
