* The 1899 "Black Eagle" two dollar bill: This bill was printed with an error that resulted in the eagle on the reverse being printed in black instead of the usual brown. Only a handful of these bills are known to exist, and they are considered to be among the most valuable paper currency notes in the world.
* The 1928 "Hawaii" two dollar bill: This bill was issued specifically for circulation in the Territory of Hawaii. Only about 20,000 of these bills were ever printed, and they are now quite rare.
* The 1976 "Bicentennial" two dollar bill: This bill was issued in 1976 to commemorate the 200th anniversary of the signing of the Declaration of Independence. The bill features a unique design that incorporates elements from the Declaration of Independence, the Liberty Bell, and the American flag.
* The 2003 "Buffalo" two dollar bill: This bill was issued in 2003 as part of the United States Mint's 50 State Quarters Program. The bill features a design based on the Buffalo nickel, which was minted from 1913 to 1938.
These are just a few examples of rare two dollar bills. Many other rare and valuable two dollar bills exist, and they can be a fascinating and rewarding hobby to collect.
