US-currency

American currency is called US dollar and coin is called US cents.In the early days of the nation, before and just after the revolution, Americans used English, Spanish, and French money.
The Massachusetts Bay Colony issued the first paper money in the colonies which would later form the United States.
American colonists issued paper currency for the Continental Congress to finance the Revolutionary War. The notes were backed by the "anticipation" of tax revenues. Without solid backing and easily counterfeited, the notes quickly became devalued, giving rise to the phrase "not worth a Continental."
Also to support the Revolutionary War, the continental Congress chartered the Bank of North America in Philadelphia as the nation's first "real" bank.
The Continental Congress determined that the official monetary system would be based on the dollar, but the first coin representing the start of this system would not be struck for several years.
After adoption of the Constitution in 1789, Congress chartered the First Bank of the United States untill 1811 and authorized it to issue paper bank notes to eliminate confusion and simplify trade. The bank served as the U.S. Treasury's fiscal agent, thus performing the first central bank functions.
The federal monetary system was established with the creation of the U.S. Mint in Philadelphia. The first American coins were struck in 1793.
The second Bank of the United States was chartered for 20 years until 1836.
With minimum regulation, a proliferation of 1,600 local state-chartered, private banks now issued paper money. State bank notes, with over 30,000 varieties of color and design, were easily counterfeited. That, along with bank failures, caused confusion and circulation problems.
On the brink of bankruptcy and pressed to finance the Civil War, Congress authorized the United States Treasury to issue paper money for the first time in the form of non-interest bearing Treasury Notes called Demand Notes.
Demand Notes were replaced by United States Notes. Commonly called "Greenbacks," they were last issued in 1971. The Secretary of the Treasury was empowered by Congress to have notes engraved and printed, which was done by private banknote companies.
The design of U.S. currency incorporated a Treasury seal, the fine line engraving necessary for the difficult-to-counterfeit itaglio printing, intricate geometric lathe work patterns, and distinctive linen paper with embedded red and blue fibers.
Gold Certificates were issued by the Department of the Treasury against gold coin and buillion deposits and were circulated until 1933.
The Department of the Treasury established the United States Secret Service to control counterfeits, at that time amounting to one-third of circulated currency.
National Bank Notes, backed by U.S. government securities, became predominant. By this time, 75 percent of bank deposits were held by nationally chartered banks. As State Bank Notes were replaced, the value of currency stabilized for a time.
The Department of the Treasury's bureau of Engraving and Printing started printing all U.S. currency, although other steps were done outside.
The Department of the Treasury was authorized to issue Silver Certificates in exchange for silver dollars. The last issue was in the Series of 1957.
The Department of the Treasury's Bureau of Engraving and Printing assumed all currency production functions, including engraving, printing, and processing.
After 1893 and 1907 financial panics, the Federal Reserve Act of 1913 was passed. It created the Federal Reserve System as the nation's central bank to regulate the flow of money and credit for economic stability and growth. The system was authorized to issue Federal Reserve Notes, now the only U.S. currency produced and 99 percent of all currency in circulation.
Currency was reduced in size by 25 percent and standardized with uniform portraits on the faces and emblems and monuments on the backs.
Paper currency was first issued with "In God We Trust" as required by Congress in 1955. The inscription appears on all currency Series 1963 and beyond.
A security thread and microprinting were introduced, first in $50 and $100 notes, to deter counterfeiting by advanced copiers and printers. If you want to know more about US currency click on the following LINK
