US Banknotes

The date of any dollar is at the center bottom.

No such bill ever existed. There was a series of $100,000 gold certificates that were used for Federal Reserve Bank transactions, but they were never circulated.

The largest circulating bills were $500, $1000, $5000, and $10,000 bills, but these have not been printed since 1945 (in the 1934-date series) and are removed from use when they enter the banking system. The surviving bills often command a huge premium as collectible items. There are still tens of thousands of $500 and $1000 bills in public hands.

The largest bill being printed now is the $100 Federal Reserve Note bearing the portrait of Benjamin Franklin.

Silver certificates were a form of paper currency backed dollar-for-dollar by silver on deposit with the US Treasury. Silver certificates were issued in denominations of $1, $2, $5, $10, $20, and $50 although 1's and 5's were by far the most common. They were usually printed with blue seals.

The government could only issue as many dollars' worth of silver certificates as they had silver metal in the vaults. They were also exchangeable for a fixed amount of silver metal. At various times you could get a dollar's worth of silver coins or silver bullion in exchange. By the 1960s demand for silver skyrocketed and the government was forced to deregulate its price. To prevent people from "gaming" the system by exchanging metal back and forth for bills and skimming the difference due to price changes, the Treasury discontinued printing silver certificates and stopped redeeming existing ones for silver. Since the 1970s all US bills have been issued as Federal Reserve Notes.

They're technically still legal tender and very occasionally show up in change, but in general they're worth more to collectors than face value. Many $1 silver certificates are only worth a bit more than face value, sometimes as little as a 25 cents extra, though. Other denominations from the late 19th and early 20th do carry a higher premium.

Two cent pieces were minted from 1864 to 1873 so you almost certainly meant to ask about 1864 rather than 1964. Please see the Related Question for more information.

Despite many Internet rumors about why the portraits on US coins and bills face a particular direction, it's purely artistic license.

The portraits are generally inspired by paintings or engravings, so whichever direction the individual faced there is simply reproduced on the coin or bill. For example, the famous Lincoln penny was designed by the sculptor Victor D. Brenner. He had already created a medal honoring Lincoln, and he merely modified the image slightly to adapt it to the front of the cent.

The blue seal indicates your bill is a silver certificate, a form of paper money issued until the early 1960s. Please see the question "What is the value of a 1935 A US 1 dollar silver certificate?" for more information.

Please check again and post a new, separate question. The US didn't print any $1 bills dated 1933, only $10 bills.

Modern US bills are printed on a special paper made from a blend of 75% cotton and 25% linen.

Please check your bill again. All HAWAII-overprint bills had brown seals rather than red, and "A" was the highest series letter used on $20 bills.

There's more information at the question "What is the value of a 1934 US 20 dollar bill with HAWAII on it?".

US bills have several letters on them, each with different meanings.

If you're referring to a letter with a small number next to it, like B1, that's a plate position number. You'll find the same thing on other denominations as well. Bills are printed in large sheets which are then cut apart to make individual bills. The position numbers indicate where in the grid of bills each one was located.

If you're referring to the large letter inside the Federal Reserve Seal, that appears only on current $1 and $2 bills and is the code for which Federal Reserve District distributed the bill (but not printed it - all bills are printed in Washington or Fort Worth). Other bills have the letter code incorporated into their serial numbers but not inside the Federal Reserve seal.

the serial number does not match the series

Yes. 1990 was the first year security strips were incorporated in $100 bills.

The US did not make silver certificates in 1740.

it was on the 1 dollar bill

The first federally-issued $2 bills were printed in 1862. They were issued as United States Notes, a now-obsolete form of currency.

Only one series of 1976 $2 bills was printed, so none of them would have a series letter. You're probably referring to the Federal Reserve District letter; the series letter is always next to (below or to the right) of the date.

In any case 1976 $2 bills were printed in large numbers so even today they're generally only worth face value.

The US didn't print any $100 bills (or any other denominations, for that matter) dated 1955. Please check your bill again and post a new, separate question.

More information is needed. Please check your bill again for its date and see the question "What is the value of a [date] US 10 dollar bill?" for more information.

The bill was distributed through the Cleveland Federal Reserve Bank but wasn't printed there. Depending on its date it could have been printed in Washington or Fort Worth.

Depending on how you define "type", there have been at least 15 major varieties of US $2 bills since the denomination was first printed in 1862. Within those varieties there have been other more minor changes resulting in more than 2 dozen differences.

Before all bills were standardized in 1928, $2 bills were printed as United States Notes, Silver Certificates, Treasury Notes, and National Currency Notes. Several of those series had multiple designs.

Starting in 1928, all $2 bills were printed as United States Notes with red seals. Bills were further standardized in 1953, and $2 bills were again redesigned. The 1963 issue was modified to include the motto In "God We Trust" on the back.

United States Notes were discontinued in the late 1960s, and $2 bills were converted to Federal Reserve Notes in 1976. As part of the Bicentennial, the reverse was completely redesigned and now shows an interpretation of Trumbull's painting of the signing of the Declaration of Independence.

No, but if it holds any numismatic value you may be better off.

No US bills are dated 1965. If your bill's date is 1963, please see the Related Question for values.
