The Sacagawea Golden Dollar Coin
The Sacagawea Dollar was minted by the US Treasury from 2000 through 2008. What year of mintage did you have in mind?
The Sacagawea & Presidential series of dollar coins are made from copper, zinc, nickel and manganese. Eisenhower and Susan B. Anthony dollar coins are copper-nickel. The older REAL silver dollars are silver and copper.
If you mean a US one dollar Sacagawea coin, only proof and collectors coins sold from the Mint have more than face value. Remember, the coins are made of brass, not gold.
The first year of issue for the Sacagawea dollar was in 2000.
Sacagawea and Presidential dollar coins are legal tender anywhere in the US and should be accepted in payment by any store.The only limitations on their use might be vending machines that haven't yet been modified to accept dollar coins.
The year 2000 saw the introduction of the unpopular Sacagawea dollar coin. Being the first year of a new issue, it had the highest mintage of any year it's been around. Between Philadelphia and Denver, there were nearly 1.3 billion of them minted.
Sacagawea dollar coins are common and worth face value.
The coin is a SACAGAWEA dollar NOT a S.B.A. dollar. 1999 was the last year for the S.B.A. coins. 2000 is the first year for the Sacagawea dollar. It's just a dollar, spend it.
