Why are there two green stars on the front on some dollar bills?

From the Bureau of Engraving and Printing:\n"When an imperfect note is detected during the manufacturing process after the serial number has been overprinted, it must be replaced with a new note. A 'star' note is used to replace the imperfect note. Reusing that exact serial number to replace the imperfect note is costly and time consuming. The 'star' note has its own special serial number followed by a star in place of a suffix letter.\n\n"The serial number of the imperfect note that was removed is not used again in the same numbering sequence."

This is definitely an urban legend.\nIn fact, Canada does not currently have bank notes for either one or two dollar denominations.

U.S. currency features something known as "series dates." A series date does not indicate the year a particular bill was printed, but rather the date of the design featured on that bill. That is, if the $5 bill were redesigned in 1929, all subsequent $5 bills issued using that design would be marked "Series 1929," regardless of when they were actually printed. (When a minor change is made to a bill's features — such as a substitution of signatures due to the appointment of a new Treasurer of the United States or Secretary of the Treasury — the series year remains the same, but a letter is appended to it. Thus a minor change to "Series 1929" currency would result in bills marked "Series 1929A.") \n\nSmall wonder, then, that some people assumed the 2006 release of newly-redesigned $10 bills bearing a legend reading "Series 2004" was the product of some sort of printing error. \n\nThe series date isn't an error, though. Although the most recent re-designs of the $10, $20, and $50 bills were authorized for 2004, the release of the denominations incorporating these new designs was (as in the previous wave of currency re-designs in 1996-2000) staggered across several years. Thus, although all three denominations bearing the latest designs are technically "Series 2004" bills, the newest $20 bills were first put into circulation at the end of 2003, the new $50 bill was first released at the end of 2004, and the new $10 bill wasn't issued until March 2006. Confusing, perhaps, but not a mistake as far as the U.S. Bureau of Engraving and Printing is concerned.

You can find them on eBay, but they cost more than $500.00.\n\n-Cory\n\n\nOn July 14, 1969, David M. Kennedy, the 60th Secretary of the Treasury, and officials at the Federal Reserve Board announced that they would immediately stop distributing currency in denominations of $500, $1,000, $5,000 and $10,000. Production of these denominations stopped during World War II. Their main purpose was for bank transfer payments. With the arrival of more secure transfer technologies, however, they were no longer needed for that purpose. While these notes are legal tender and may still be found in circulation today, the Federal Reserve Banks remove them from circulation and destroy them as they are received.

No.  That is called a "Star note" and there are many in circulation.

There are several denominations of currency notes that are no longer produced. These include the $500 bill with the portrait of William McKinley, the $1,000 bill with a portrait of Grover Cleveland, the $5,000 bill with a portrait of James Madison, the $10,000 bill with a portrait of Salmon P. Chase, and the $100,000 currency note bearing a portrait of Woodrow Wilson.

Find some collectors of misprint currency. Many of them will pay quite a lot of money for things like this. Upwards of 300+ dollars is not unheard of. If nothing else, keep it.

I think the generic currency sign (¤) may have something to do with it too.

I believe that the last printing of $2 bills was in 2003 so they are not as rare as you might believe.  If you were to go to your local bank and ask for a $2 dollar bill they should have it. Now as to why they are so rare it’s because people collect them. I'm guilty of hording every $2 dollar bill that comes my way. As to the worth, we'll it’s just a $2 dollar bill.

the stars are actually the front of the flag. they are faced opposite to symbolize marching into battle instead of runnin away from it.

You'd have to tell me the denomination. As an example in this 20 thousand bolivares bill http://www.kcshop.com/fc/p.php?pic=F5182 you can see the face of Andres Bello in one side, and a Guacamaya (big parrot), an orquid (national flower) and Angel Fall (the biggest in the world, I think). That's just one example, there are a lot more.

Because the matrices that hold the electronic parts that we call "chips" and "motherboards" (which are just really big, complex chips) are green. It's a computer reference.

take it to a bank and have them check it. \n\n2.00 bills are older, so the watermark may not exist, if they were made some time ago.\n\nGenerally the feel of a counterfeit bill is smoother than a true bill. \n\nThe Bank will know. \nGood luck.
