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.

No US coin, including the half dollar has a crown stamp on it when it comes from the mint. Instead, if you have a US half dollar with a crown stamp in it, it was done either by a private company or individual. These stamps generally add no value to your coin and it is just worth what a damaged example of whatever year of half dollar you have is worth.
Two-dollar bills are generally worth two dollars. Adding a postage stamp to it wouldn't affect the value if the bill. The stamp itself, if rare, might be worth more than two dollars.
