This is a US dollar coin from 2009 or later. At the same time the Presidential Dollar series is being released, one new "Native American" coin is released every year. The first in this series was released in 2009 and is the one you mention.
To clear up several questions and misconceptions:
> Yes, the coin is made of brass. Gold is FAR too expensive to make into large circulating coins.
> The coin DOES have a date, it's on the coin's edge.
> The Native American woman depicted on the front of the coin is an interpretation of the famous guide Sacajawea rather than Pocahontas.
> The woman on the back is a generic image.
It has a picture of Liberty with a winged helmet on the obverse ("heads") side and an bundle of sticks with an axe on the reverse ("tails") side.
The reverse of any coin is its back. The portrait is on the obverse, or front.
Technically, the two surfaces of a coin are known as the obverse (front) and reverse (back). Informally, they are known as heads or tails. One side is called the obverse the other side is called the reverse. The obverse is general the side which features a monarch or president.
Please be more specific what type.
Former U.S. President Thomas Jefferson is featured on the obverse of the note. The reverse of bills dated 1976 and later shows a somewhat modified version of Trumbull's painting of the signing of the Declaration of Independence. Older bills show a picture of Jefferson's home, Monticello.
All coins have two sides, an obverse and a reverse. The obverse is the front or the "heads" side, the reverse is the back or the "tails" side.
The British Halfpenny coin featured Britannia on the reverse for hundreds of years. The obverse featured the reigning King or Queen.
It has a picture of Liberty with a winged helmet on the obverse ("heads") side and an bundle of sticks with an axe on the reverse ("tails") side.
Those symbols are the obverse and reverse of the Great Seal of the United States. The eagle is the obverse and the pyramid is the reverse.
Normally the "heads" side is the obverse. That categorization is contentious when a coin bears the picture of the reigning monarch on one side, such as coins from Canada, Britain, and Australia. In those cases numismatists tend to call the design side the obverse and the portrait side the reverse, but that's not universal.
"Obverse" refers to the front of the coin (usually the side with the portrait), as versus the "reverse", or back, of the coin.
The reverse of any coin is its back. The portrait is on the obverse, or front.
The term "reverse" refers to the back side of a coin, as opposed to the "obverse", or front side. On US coins, the obverse side is the one with the portrait and (except for the presidential dollars) the date. On foreign coins, it is not always easy to determine which side is the obverse and which is the reverse, although a good rule of thumb is that the side with the portrait, crest, or name of the country is probably the obverse.
