Dollar Composition

What is a Dollar?

The Dollar of the Republic of the United States of America as established originally by the Constitution of the Republic of the United States of America and first promulgated under the Coinage act of 1792 (Coinage Act) is a weight of silver or gold; simple as that.  Exactly, as provided in the Coinage Act, a Dollar is three hundred and seventy-one grains and four sixteenths parts of a grain of pure silver, or four hundred and sixteen grains of standard silver, exactly the composition of the Spanish milled dollar that circulated at the time and served as the basis on monetary transactions.

The Coinage Act established that a Ten Dollar coin, designated the Eagle, would contain two hundred and forty-seven grains and four eighths of a grain of pure, or two hundred and seventy grains of standard gold. Fractional coins thereof, such as the Half Eagle with a Five Dollar denomination, carried the exact corresponding ratio of gold.  That is, the Half Eagle contained one half of 247/270 grains of gold.

The Dollar was last minted between 1792 and 1935; no Dollars have been made since 1935.

Everything else produced with the word Dollar, or dollar, is either a promissory note, scrip, unit of account, obligation, fiat, tender, or method of settlement.

The Republic of the United States of America ceded authority and responsibility for producing the nations coinage to the UNITED STATES OF AMERICA CORPORATION (US) via the 14th Amendment in 1868.  The UNITED STATES OF AMERICA CORPORATION continued to produce Dollars via the US Mint as administered by the US Congress until ceding such Authority to the FEDERAL RESERVE CORPORATION on December 23, 1913 via the Federal Reserve Act.  The US Mint continued to produce Dollars as administered by the FEDERAL RESERVE CORPORATION until 1935, at which point the UNITED STATES OF AMERICA CORPORATION declared de-facto bankruptcy via re-organization and surrendered the power to create both Constitutional money and legal tender.

DOLLAR    Composition Summary:

Pre-1792

Before the united states began minting its own coinage, the settlers used Spanish Reales, German Thalers and the various British coinage. 

1794-1795

The Congress of the Republic of the united states of America authorized the Mint to produce Dollar coins of 416 grains silver at 0.8924 fine.
