United States Paper Money is currently printed in $1, $2, $5, $10, $20, $50, and $100 bills. This is not always the way it was. In 1861, when U.S. currency started being printed, in addition to the current bills, there were $500, $1,000, and $5,000 bills being printed as interest bearing notes. Later, in 1865, $10,000 Gold Certificates started being put out into circulation.

These bills were printed as small-sized notes starting in 1929. The $500 bill had a portrait of the twenty-fifth U.S. President, William McKinley. The $1,000 bill showed a picture of Grover Cleveland, the twenty-second and twenty-fourth U.S. President. The $5,000 bill had a picture of James Madison, fourth President of the United States. Salmon P. Chase, a American Politician, was shown on the $10,000 bill. These bills were printed mainly in green and black ink. Production of these bills ended in 1945 and on July 14, 1969, the Federal Reserve System officially discontinued them. Today, these bills are super rare and worth quite a lot of money.

The last of the Former United States Paper Money is the $100,000 bill. It displayed a portrait of twenty-eighth U.S. President, Woodrow Wilson, on the obverse and was printed in orange ink on the reverse. This bill was made only as a Gold Certificate of Series of 1934 and used for only government business. The series stopped being printed in 1940.

These bills were mainly printed for the use of banks and the Federal Government for big financial trades. It is unlikely that bills this large will ever be produced again because of all the problems related to counterfeiting and bad use like illegal drug deals. Credit cards and electronic money have provided another reason that making these bills would be pointless.

In this day and age, Canada has only five different banknotes ($5, $10, $20, $50, $100) that are currently being printed. This is because large amounts of money can be electronically transferred and small amounts, such as a $1, have been replaced by coins. Due to all of this, the twenty-five-cent bill, the one-dollar bill, the two-dollar bill, the four-dollar bill, the twenty-five-dollar bill, the five-hundred-dollar bill, and the thousand-dollar bill have been withdrawn from circulation.

The twenty-five-cent bill was issued  in 1870 by the Dominion of Canada. It was also known as a shinplaster. This bill was intended to be around for only a short time, but was reissued in 1900 and 1923 then recalled by the Bank of Canada in 1935.

The one-dollar bill stopped being printed in 1989 and was replaced with the loonie.

The two-dollar bill stopped being printed in 1996 and was replaced by the toonie. These are not seen very often in circulation anymore, although there was over 109,000,000 notes that were not returned to the Bank of Canada in 2006.

The four-dollar bill started being issued in 1871 by the Dominion of Canada. It was last issued in 1904 and was withdrawn in 1912 to be replaced with the five-dollar bill.

The twenty-five-dollar bill was issued by the Bank of Canada in 1935 to commemorate the silver jubilee of King George V. It was a limited release not printed in big amounts.

In 1935, the Bank of Canada issued  the five-hundred-dollar bill. It has not been printed again since.

The thousand-dollar bill stopped being printed in 2000. The demand for this bill was low and it was used for money laundering so it was withdrawn.
