Please take another look at your coin and post a new, separate question with more details that would help determine its country of origin. The dollar didn't become a common unit of currency until it was adopted by the new US government at the time of the Revolution, a century and a half after 1621.
No 1621 dollar coins were made, look at the coin again and post new question.
If it's a copy, it's not worth much of anything. It's made of an inexpensive base metal, probably zinc.
Yes, there were many dollar coins with errors. One of the best known dollar error coin was the Sacagawea dollar coin and Washington quarter mule error. Only 12 of these coins were made and they can be up to $100,000.
The U.S. has never made a gold half dollar coin. Look at the coin again and post new question.
If I understand the question, you have a Sacagawea dollar coin with no date on the obverse (front) of the coin and you think it should have a 2000 date on it? The coin was made after 2008. From 2009 to date, the year the coin was struck in is on the edge of the coin.

It depends on when the coin was made, US one dollar coins have been made from gold, silver, copper-nickel and manganese brass. Post new question with a date.
It's just a dollar coin with no gold in it and is in circulation today.The gold color is from the metal it's made from.
The bicentennial dollar coin is still worth one dollar.
No. There is no precious metal in any Australian general circulation coin. The Australian One and Two Dollar coins are made from an aluminium-bronze alloy.
The word COPY means simply that - your coin is a replica, not an original, so it's only worth the value of the base metal that it's made of - perhaps a dollar or two.
The first US dollar coin was made in 1794.
The original dollar coin was made of Silver. The current dollar coins are made of Copper, Zinc, Manganese, and Nickel by the United States mint. The Morgan Silver Dollar is prized by coin collectors.
1841
No, the last 1 dollar gold coin was made in 1889.
The "mini coin" gives it away. It's a privately-made replica of a rare 1840 dollar, but not rare itself. It's only worth the value of whatever metal it's made from. Unless the coin's packaging states that it's made of silver, it's probably only silver-plated.
Eisenhower was on the dollar coin from 1971 to 1978. J. F. Kennedy is on the half dollar. Whichever one you have, assuming the coin is from circulation it's only worth face value. They're made of copper-nickel, not silver, so they have no precious metal content.
