Silver Dollar coins have been
minted in the United States in gold, silver, and base metal
versions. Silvers, the first dollar coin issue, were
minted beginning in 1794.
The term silver dollar is often used for any large white metal
coin issued by the United States with a face value of one
dollar; although purists insist that a dollar is not silver
unless it contains about 90% or more of silver. Gold and
gold-colored dollars have also been produced by the United
and Presidential dollars are usually referred to as "golden",
despite not containing any gold.
Dollar coins have found little popular acceptance in modern
circulation in the United States, despite several attempts since
1971 to phase in a coin in place of the
one dollar bill. This
contrasts with currencies of many other developed countries,
where denomination of similar value is only in coin, such as the
Canadian loonie and toonie, British 50 pence coin (as well as
the 1 pound and 2 pound British coins), the 1 and 2 Australian
Dollar coins, the 50 New Taiwan dollar coin, 100 Japanese yen
coin, 1 euro coin and 2 euro coin.
