UNITED STATES MONEY, sometimes called Federal Money, is the currency of the United States. NOTE. 1 = 10 = 100 = 1000 10000 The terms eagle and dime are seldom used in computation; eagles and dollars being read collectively and called dollars, and dimes and cents being called cents; thus, 3 eagles and 5 dollars are called $35, and 4 dimes and 3 cents are called 43 cents. 177. What is United States Money? Repeat the Table. Are the terms eagle and dime much used?. 178. The currency of the United States being based upon the Decimal Notation, most of the necessary rules for operations in this currency, and also many examples, have already been given; but the importance of the subject justifies a separate consideration of it. 179. A coin is a piece of gold, silver, or other metal, stamped by authority of the General Government, to be used as money. 180. The coins authorized by our Government, and stamped at the U. S. Mint, are the following: 181. Gold and silver, for coinage, are hardened by being mixed with harder and cheaper metals. These cheaper metals, when combined with the gold and silver, are called alloys. 182. Carat is a term used in indicating the purity or fineness of gold. If a piece of metal is pure gold it is said to be 24 carats fine; if 3 of it are gold, and the remaining is alloy, it is 23 carats fine; etc., etc. 183. The standard purity of gold and silver coin at the U. S. Mint, is of pure metal and alloy. The alloy in silver coin is pure copper. The alloy in gold coin is copper and silver, the silver not to exceed the copper. (a) The new cent is composed of 88 parts of copper for 12 parts of nickel. 178. On what is the currency of the U. S. based? 179. What is a coin? 180. What gold coins are authorized by our Government? What silver coins? Of what is the cent made? 181. What is alloy? For what used? 182. For what is the term carat used? Pure gold is how many carats fine? 183. What is the standard purity of gold and silver coin? What is the alloy for silver? What for gold? What part of the new cent is nickel? NOTE 1. The copper cent is still in use, but is no longer coined at the U. S. Mint. NOTE 2. The mill is not coined. NOTE 3. Other pieces of money, as the 50-dollar gold piece, the half and quarter dollar gold pieces, are in use to some extent, but are not legal coin. NOTE 4. The greater part of the money in general use, consists of bank bills, which are much more convenient for most purposes than gold and silver. 184. The weight of the eagle is 258 grains, Troy. The silver dollar weighs 4123 grains, but the smaller coins are not so heavy in proportion to their value; thus, the half dollar weighs only 192 grains; the quarter, only 96 grains, etc. The new cent weighs 72 grains. NOTE. These standards of weight and purity are regulated by Congress, and may be changed at any time. 185. In this currency, the dollar is the unit, cents and mills being decimals of a dollar; thus, $3.62 represents three dollars and sixty-two cents; $4.085 represents four dollars, eight cents, and five mills, etc. NOTE. Figures at the right of the third decimal place, represent parts of mills; thus, $5.3627 5 dollars, 36 cents, 2 mills, and of a mill. REDUCTION. 186. The reduction of U. S. Currency is very simple. Dollars are reduced to cents by annexing 'two ciphers (Art. 62), and to mills by annexing three ciphers; thus $4400 cents = 4000 mills. Dollars and cents are reduced to cents by removing the decimal point; thus, $3.56= 356 cents. Dollars, cents, and mills 183. Is the mill coined? What of other pieces of money? What of paper money? 184. What is the weight of the eagle? Of the silver dollar? Half dollar? By whom is the standard of weight and purity fixed? 185. What is the unit in this currency? What are cents and mills? What are figures at the right of the third decimal place? 186. How are dollars reduced to cents? How to mills? How are dollars and cents reduced to cents? How dollars, cents, and mills to mills? are reduced to mills in the same way; thus, $5.468=5468 mills. 187. Cents are reduced to dollars by pointing off two decimal places (Art. 81). Mills are reduced to dollars by pointing off three decimal places; thus, 3768 cents = $37.68; 3768 mills $3.768. 7. Reduce 564 cents to dollars. 9. Reduce 87694 cents to dollars. 10. Reduce 76843 mills to dollars. Ans. $5.64. Ans. $3.692. 188. Addition, Subtraction, Multiplication, and Division of U. S. currency, are performed precisely as the corresponding operations in Decimal Fractions. 4.
