Question: How many stars are on the flag of the country owning banks of the issuer of the dollar banknotes since 1914?

<P0-S0> Today, USD notes are made from cotton fiber paper, unlike most common paper, which is made of wood fiber. <P0-S1> U.S. coins are produced by the United States Mint. <P0-S2> U.S. dollar banknotes are printed by the Bureau of Engraving and Printing and, since 1914, have been issued by the Federal Reserve. <P0-S3> The "large-sized notes" issued before 1928 measured 7.42 inches (188 mm) by 3.125 inches (79.4 mm); small-sized notes, introduced that year, measure 6.14 inches (156 mm) by 2.61 inches (66 mm) by 0.0043 inches (0.11 mm). <P0-S4> When the current, smaller sized U.S. currency was introduced it was referred to as Philippine-sized currency because the Philippines had previously adopted the same size for its legal currency. <SEP> <P1-S0> in 1970 the country switched its currency from the bermudian pound to the bermudian dollar, which is pegged at par with the us dollar. <P1-S1> us notes and coins are used interchangeably with bermudian notes and coins within the islands for most practical purposes; however, banks levy an exchange rate fee for the purchase of us dollars with bermudian dollars. <P1-S2> bermudian notes carry the image of queen elizabeth ii. <P1-S3> the bermuda monetary authority is the issuing authority for all banknotes and coins, and regulates financial institutions. <P1-S4> the royal naval dockyard museum holds a permanent exhibition of bermuda notes and coins. <SEP> <P2-S0> the u.s. constitution provides that congress shall have the power to "borrow money on the credit of the united states". <P2-S1> congress has exercised that power by authorizing federal reserve banks to issue federal reserve notes. <P2-S2> those notes are "obligations of the united states" and "shall be redeemed in lawful money on demand at the treasury department of the united states, in the city of washington, district of columbia, or at any federal reserve bank". <P2-S3> federal reserve notes are designated by law as "legal tender" for the payment of debts. <P2-S4> congress has also authorized the issuance of more than 10 other types of banknotes, including the united states note and the federal reserve bank note. <P2-S5> the federal reserve note is the only type that remains in circulation since the 1970s. <SEP> <P3-S0> The Federal Reserve System (also known as the Federal Reserve or simply the Fed) is the central banking system of the United States of America. <P3-S1> It was created on December 23, 1913, with the enactment of the Federal Reserve Act, after a series of financial panics (particularly the panic of 1907) led to the desire for central control of the monetary system in order to alleviate financial crises. <P3-S2> Over the years, events such as the Great Depression in the 1930s and the Great Recession during the 2000s have led to the expansion of the roles and responsibilities of the Federal Reserve System. <SEP> <P4-S0> The flag of the United States of America, often referred to as the American flag, is the national flag of the United States. <P4-S1> It consists of thirteen equal horizontal stripes of red (top and bottom) alternating with white, with a blue rectangle in the canton (referred to specifically as the ``union '') bearing fifty small, white, five - pointed stars arranged in nine offset horizontal rows, where rows of six stars (top and bottom) alternate with rows of five stars. <P4-S2> The 50 stars on the flag represent the 50 states of the United States of America, and the 13 stripes represent the thirteen British colonies that declared independence from the Kingdom of Great Britain, and became the first states in the U.S. Nicknames for the flag include The Stars and Stripes, Old Glory, and The Star - Spangled Banner.
