The series is simply the date. Sometimes people include the letter, if any, next to the date when describing the series.
Dates on US bills don't refer to when the bill was printed, but instead indicate what Treasury Secretary, US Treasurer, and/or design were present when the particular group of bills was first printed. That's the reason for the term "series".
Over the years the Treasury has changed the rules that determine a series - and sometimes even ignored its own standards. In the early 20th century a new series was usually started only when there was a significant design change, such as the new design for $1 silver certificates introduced in 1935.
The first bills in any series are usually but not always printed without a letter next to the date. The second set printed would have an "A", "B" would be on the third, and so on.
In the past a letter was added each time a new Treasury Secretary or US Treasurer took office so if the design didn't change the letters could go quite high. Those 1935 $1 SC's were issued all the way up to H.
In 1974 the rule was changed to be that a new series would start whenever a new Treasury Secretary takes office and a letter would be added only if there's a change in the Treasurer's position. As a result modern bills have much more frequent date changes and series letters haven't gone above B in most cases.
That rule has led to some anomalies too, though. For example a new 2004 series was started when the multicolor $20s were introduced, but by the time the new tens were ready there had been a change in Treasurers. The first "colorized" tens were printed as 2004-A instead of 2004. Somewhat strangely the Treasury didn't start a new series when the new purple and gray five was introduced so both the new and old designs were printed as Series 2006 bills.
Us $50 :-d
No US $20 bill carries a "G" series letter. You may be looking at the Federal Reserve District letter. The series letter, if any, on US bills is next to the date. Regardless, a date is needed in order to estimate a value. Please determine the bill's date and see the question "What is the value of a [date] US 20 dollar bill?" for more information.
Not in the US. Series dates for $2 FRN's are 1976, 1995, and 2003.
Security strips were added starting with the 1990 series.
None of them. 1950-series $10 bills remain common among collectors. There's more information at the question "What is the value of a 1950 US 10 dollar bill?".
Sorry, there is no such bill.
I would like to the current value of excellent condition of 1862 US series 268 1 dollar bill.

Check the date or rather series again. US dollar bills were not made in 2010.
Check the date or rather series again. US dollar bills were not made in 1960.
Check the date or rather series again. US dollar bills were not made in 1920.
The year the bill was printed is on every US currency note. The year will be listed to the lower right of the bust of Andrew Jackson marked as "series" (year)
C is the highest series letter on a 1953 US $2 bill. The series letter, if any, is next to the date. Please see the question "What is the value of a 1953 US 2 dollar bill" for more information.
No. There were no 2005 series bills of any denomination.
If you are saying you have a 1 Million dollar US Bill from 1996, then, no it is not real

Benjamin Franklin's portrait is still on the $100 bill, regardless of series date.
