There is no difference between the dollar and the dollar, but for historical reasons there are different versions.
Historically, the dollar was often called the dollar because it could be exchanged for an equivalent amount of gold.
The dollar is the law of the United States of America.
In 1934, the United States went off the gold standard and backed the dollar with gold.
From then on, dollars were no longer convertible into gold, but people still got used to the name of the dollar.
The dollar is the legal tender of the United States, so it is called the “dollar”, because in July 1944 it was stipulated that all countries must confirm the official price of $35 per ounce of gold set by the United States, and can turn it into gold at the official price, which means that the dollar is directly pegged to gold, so the dollar is also called the “dollar”.
