Starting from 1928, the color of the U.S. dollar is fixed, and it is linked to the type of bonds.
Silver dollar coupons, also known as silver coupons, are printed and numbered in blue. This coin can be traced back to the Brand-Ellertson Act of 1878. It is a convertible currency and is issued directly by the US Treasury. The holder can exchange silver coins at face value. 1963, the us house of representatives passed bill PL88-36 to abolish the silver purchase law, and the us treasury stopped issuing silver coupons.
This is the last 10 yuan certificate issued in the bank certificate, with the face date of 1953B.
Government bonds are red printed and numbered dollars, dating back to the American Civil War. At that time, in order to solve the problem of military expenditure, the US Congress authorized the Lincoln administration to issue unsecured and guaranteed pure credit currency-government bonds, with a maximum amount of $400 million. Later, after the end of the civil war, the national debt was retained and issued directly by the Ministry of Finance as a dollar currency until the end of the 1960s.
This is the last issue of 100 yuan certificate in American paper money, with face value of 1966A.
Since the 1970s, the United States has only issued green printed and numbered Federal Reserve bonds as American currency, so the United States bid farewell to the era of mixed issuance of various bonds. Federal reserve bonds are issued by the Federal Reserve Bank under the Federal Reserve, which is the dollar we see in circulation today. The original color of the library seal and the Federal Reserve bank note number is also blue. Since 1928, the color of the library seal and number has been changed to green, which has been used to this day. The picture shows version 20 13 1 USD.
