Probably never. Modern practice is to add a series letter only when a new Treasurer is appointed, and to start a new series year whenever a new Secretary of the Treasury is appointed.
The 2006 series started when Henry Paulson became Secretary of the Treasury but he left office when the Republicans were defeated in 2008. Once the current supply of bills runs out a new 2009 or 2010 series with Tim Geithner's signature will be printed.
If you mean the series number, there were several valid series of US dollar bills in that time frame. Specifically:Series 1999Series 2001Series 2003Series 2003ASeries 2006There were also Series 2004, 2004A, and 2006A, but those were only issued in some denominations ($20 and $50 notes for 2004; $10, $20, and $50 notes for 2004A; $100 notes for 2006A). There was also a Series 2009, but I'm not sure that those were actually released IN 2009.
The last printing was in 1945. However these bills were issued as part of the 1934 series and they carried the series date 1934 A.
As of July 2010 no series 2009 or 2010 $2 bills have been printed.
There were no series letters on 1929 bills, all of which were issued as National Currency bills. Please see the question "What is the value of a 1929 US 5 dollar bill?" for more information.
Yes they do. In 1928 a new series of currency was issued and Jackson's picture was moved from the $10 bill to the 20. Incidentally, the old series bills were noticeably larger than they are today.
Three dollar bills exist but they were never issued by the US government, although the US issued a three dollar coin from 1854 to 1889. Earlier, some colonies printed three dollar bills. When banks were allowed to print money in the early days of the US, some printed legitimate, legal three dollar bills. The Confederacy also produced three dollar bills.
The U.S. Treasury has issued various series of two-dollar bills since their introduction in 1862, with the most recent series being printed in 2013. While specific production numbers vary, it's estimated that around 1.4 billion two-dollar bills were printed overall. However, many of these bills are still in circulation, leading to a perception of their rarity. As of recent years, approximately 60 million two-dollar bills remain in circulation.
Series 1981 $100 bills have the signatures of Treasury Secretary Donald Regan and US Treasurer Angela Buchanan. Series 1981 A bills were issued when Buchanan was replaced by Katherine Ortega.
A star on a dollar bill marks it as a "replacement note". If there's a problem printing a normal press run of dollar bills, then a series of replacement notes are issued. The star simply serves to identify them.
In the 1950s, there were several different series of 10 dollar bills issued by the treasury. The series range from A through E, and have different values depending upon the series. For a series A 10 dollar bill, the value online is between 45 and 100 dollars, depending upon condition.

The first federally-issued $5 bills were printed in 1861 as "demand notes" to help finance the Civil War. The first $5 bills printed as regular-series currency appeared a year later. They were issued as United States Notes, a form of currency that was issued up till the end of the 1960s.
