US Banknotes

The paper used is a blend of 75% cotton and 25% linen, with bits of red and blue fibers mixed in.

Please check your bill again and post a new, separate question.

There are only plain, A, and B-series letters for 1957 $1 bills.

"K" is either a plate ID or part of the serial number. In either case it's not a determining factor in the bill's value. What matters is what letter if any appears next to the date. There may not be a letter, or a small A or B.

However, regardless of whether you have a 1957, 1957A, or 1957B bill, all of these are very common among collectors and retail for at most $1.50 in circulated condition.

2 dollar bill

President William McKinley. was on the 500 dollar bill

There is no "J" series. The series letter is next to the date and corresponds to the Treasury Secretary and/or Treasurer who were in office when the bill was printed. "J" is almost certainly the Federal Reserve Bank indicator letter.

In any case, your bill is worth face value to $140 depending on condition

The value of a star note is usually somewhat higher than that of a "regular" bill, but the extra value depends very much on the bill's date and condition.

If it's a modern (1976 or later) $2 bill, regular-issue ones are only worth face value so a circulated star (replacement) note will only be worth 50¢ to a dollar more. A nice uncirculated one could bring around $4.

If the bill is older please post a new question with its date and what letter if any is after the date. You don't need to copy the entire serial number.

US $2 bills carried a picture of Monticello for nearly 40 years so more information is needed. Please post a new and separate question with the bill's date and whether there's a small letter next to / under the date. You don't need to include the serial number, though.

Current circulating denominations are:

$1 - a portrait of President George Washington

$2 - President Thomas Jefferson (this denomination isn't commonly used)

$5 - President Abraham Lincoln

$10 - 1st Treasury Secretary Alexander Hamilton

$20 - President Andrew Jackson

$50 - President Ulysses S. Grant

$100 - Statesman and scientist Benjamin Franklin

At one time the US also issued $500, $1000, $5000, and $10,000 bills for general circulation and printed special $100,000 bills for use inside the government. Printing was discontinued in 1945. In 1969, banks were ordered to stop distribution of high-denomination bills as a way of combatting organized crime.

The U.S. didn't print any $2 bills dated 1961. Please check again and post a new question

The banner across the top of your bill identifies it as a United States Note. These bills were printed with red ink to distinguish them from silver certificates (blue) and Federal Reserve Notes (green). US Notes were issued directly by the federal government rather than through the Federal Reserve System. The two kinds of currency served the same purpose so production of US Notes was suspended in the late 1960s to save on printing and distribution costs.

For obvious reasons the Bureau of Engraving and Printing doesn't give out many details on the inks used to print US currency. The inks are very high quality oil-based products, but beyond that there isn't much public information available because of concerns about counterfeiting.

Federal Reserve Notes are printed by the Bureau of Engraving and Printing at facilities in Washington and Fort Worth.

Bills are distributed through the Federal Reserve banks in Boston, New York, Philadelphia, Richmond, Atlanta, St. Louis, Cleveland, Chicago, Kansas City, Dallas, Minneapolis, and San Francisco.

According the US Treasury web-site:

All denominations of paper currency notes printed since 1929 are the same size, measuring approximately 2.61 inches (6.63 centimeters) by 6.14 inches (15.60 centimeters). Each note weighs about one gram.

Please post a new, separate question with the bill's country of origin. The US didn't print any bills dated 1961.

It's an ordinary Washington bill that was altered to commemorate JFK after he was assassinated in that year.

Unfortunately it's not of interest to coin or bill collectors, though there may still be some collectors of Kennedy memorabilia who would want to add it to their sets.

what forenics analysis have you conducted on the Bond? How do you even know if its geniune? Morganthau perhaps? Phillipine orgin.. or from Jogjia? No one in the world will reedem them even if they were real. Im sorry to discourage you my fellow Indonesian.

A one dollar bill weighs approximately 1 gram, so a billion (10^9) bills would weigh 1 billion grams. Moving the decimal point gives you 1 million kg or 1000 tonnes.

In US units that's approximately 2204000 lbs or 1102 tons if you do the math and conversions.

According to the Treasury, 7 years on average.

The layout of the back is essentially identical to modern $1 bills.

The front is similar but with some obvious differences, such as the words "Silver Certificate" and "In silver payable to the bearer on demand"; a blue seal and serial numbers; and the absence of a Federal Reserve seal.

Beyond that, an actual picture is much more instructive. While it's not Answers.com policy to say "use the Internet", that's the best approach in this case. You can use any major search engine to look for "1957 1 dollar silver certificate images" or a similar phrase.

Only a few 1934 A $10000 bills were printed and none were released to general circulation. It's almost certain you have a replica, but it might be worth having it examined in person by a currency dealer or appraiser.

Only one series of 1976 $2 bills was printed, so none of them would have a series letter. A series letter is always next to (below or to the right) of the date. If the "K" is in the Federal Reserve Seal, it's the indicator letter for the Federal Reserve Bank that distributed the bill.

Please see the question "What is the value of a 1976 US 2 dollar bill?" for more information.

Please check again and post a new, separate question. There were only 3 series of 1957 $1 bills - plain, A, and B. The series letter if any is next to the date.

In any case most 1957 $1 silver certificates are only worth $1.25 to $2.00 in average condition, regardless of series letter.
