The 1976 L US $2 dollar bill was part of the Federal Reserve's "Bicentennial" series of banknotes, which were issued in commemoration of the 200th anniversary of the United States Declaration of Independence. The L designation indicates that the bill was printed at the Federal Reserve Bank of San Francisco.
1976 L US $2 dollar bills are not particularly rare, but they are not as common as some other banknotes from the same series. This is because the $2 denomination is not as widely used as other denominations, such as the $1 or $5 bill. As a result, 1976 L US $2 dollar bills can be of interest to collectors and may be worth more than their face value.
If you have a 1976 L US $2 dollar bill that you are considering selling, it is a good idea to have it appraised by a professional numismatist to determine its exact value.
