This is the unit of value not only of the United States, but of several other countries.
The United States " dollar " must contain 25.8 grains of standard gold, .900 fine; the amount of fine gold being 23.22 grains, the remainder of the weight being an alloy of copper. Although the gold dollar is actually the unit and standard of value, its coinage was discontinued under authority of the Act of September 26, 1890, and the only coined dollar which we have in general circulation at present is of silver, ącon-taing 4 1/2 grains of standard silver, .900 fine, or 371 1/4 grains of fine silver, the balance, 41 1/4 grains, being a copper alloy.
The dollar of British Honduras, Liberia, and Columbia is of equal value to our own; that of the British possessions in North America, except Newfoundland, the same, the latter being equal to $1.014 United States money. In Hong-kong there are various dollars in circulation, the Hong-kong dollar, so called, and the British dollar, both equal - April 1, 1906 - to $.515; also Mexican dollars, equal to $0.519 United States money. These being silver dollars, however, their value in our coinage fluctuates with the market price of silver.
