United States. Trade Dollar 1876

The American dollar was issued in 1873 specifically for trade with China, since it maintained the silver standard unlike other countries. Therefore, it also indicates the silver content in grains: "420 grains 900 FINE."
And although they were not officially released into the US domestic market, they were still legal tender in the United States. However, in 1876, silver fell a lot relative to gold. The coins created for foreign trade were bought for an amount equivalent to 80 cents, brought to the United States and purchased at face value. Therefore, Congress passed a law that abolished their status as legal tender in the United States. This is the only coin minted in the United States in millions of copies with the inscription "UNITED STATES of AMERICA", but it is not a means of payment in its own country.
From 1879 to 1885, these coins were produced in small editions for collectors.
Minting only 456,150 specimens.
